1Zhejiang Normal UniversityRiding Comfort Evaluation of Urban Rail Transit Based on Cloud Model
The ride comfort of urban rail transit is a kind of comprehensive experience evaluation of passengers in the process of riding urban rail transit based on their subjective feelings. Aiming at the fuzziness in the process of passenger comfort evaluation of urban rail transit, a new method for passenger comfort evaluation of urban rail transit based on the combination of CRITIC method and Cloud model to deal with uncertain information is proposed. It is expected that this method can overcome the subjective problem of index weight selection in fuzzy evaluation and realize the reasonable transformation between qualitative and quantitative problems. The effectiveness and rationality of this method are verified by taking passenger comfort evaluation of a subway line in Hangzhou city as an example. In this way, the application of cloud model in urban rail transit is broadened. Then the measures and suggestions for improving the riding comfort of urban rail transit are putting forward. It lays a certain foundation for further research on riding comfort of urban rail transit.
2Tongji University Subway Train Onboard Filters
This work designs a filter which can be installed at the bottom of subway car. Horn-shaped air inlet and rotatable air inlet door are symmetrically arranged. The air inlet door will open under the wind pressure. A porous baffle is set behind the air inlet door to slow down the wind speed. Dust removal bags are set behind the porous baffle to intercept the particles. A reverse blow pipe is set on the upper position with nozzles on it, through which the compressed air can blow down the particles accumulated outside the bag. A dismountable dust collecting device is set at the bottom to collect particles.
When the subway train runs, the air doors on the windward side open under wind
pressure, and the dusty air in the tunnel enters into the device and hits the baffle. The large particles are separated under the inertial action and fall on the dust collecting device. Then the air collides with the dust remove bags. The purified air flows out from the bag outlet, and then leaves the dust collecting device on the top.This work makes use of the kinetic energy of the subway train when it runs and fan or power supply is needed. It can absorb the particles generated by friction during the subway operation, purify the tunnel environment, and protect the health of subway commuters and staff.
3Tongji University Break the Impasse on Bus System Benefits:Evaluating and Dispatching Methods
With the rapid growth of the national economy and the improvement of living standards, people’s travel demand is mushrooming, causing serious traffic jams and air pollution. Public transit priority has become a worldwide consensus, which can reduce the use of private motor vehicles and promote healthy and sustainable urban development. However, with conventional single-type and fixed-route buses following the fixed departure interval, the relatively fixed supply cannot meet the time-varying travel demand. Bus overload and empty driving are both happening. Nowadays, in the era of big data and the Internet of Everything, many refined management methods and innovative service modes are springing up. The accurate and usable evaluating system for supply-demand matching and space-time resource utilization, and the intelligent dispatching methods may become an important breakthrough to improve the efficiency of the public transit system.
Comprehensively considering the two dimensions of time and space, two core indicators of Supply-Demand Matching and Space-Time Occupancy are proposed to describe the degree of matching of travel demand and transportation capability and the degree of occupation of road resources. The proposed dual-objective evaluating system can effectively assess the waste of transportation capability and road resource caused by inefficient dispatching schemes. Furthermore, a new intelligent bus dispatching method and a dispatching system are developed, which can adjust the supply dynamically according to the fluctuating demand. Flexible departure intervals, different bus types and stop-skipping strategies are adopted. Thus, the limited road space-time resources can be used effectively to serve actual demands. The efficiency, level of service and sustainability of the public transit system are expected to be truly improved
4Tongji University Intelligent Auxiliary Decision-making System for Urban Rail Transit Network Operation
With the popularization of urban rail transit network operation, the demand for network passenger flow has grown rapidly. At the same time, the contradiction between the demand and the insufficient capacity supply is becoming more and more prominent, which is mainly reflected in the imbalance of network capacity matching and the retention of passenger flow at transfer nodes. The key problem is that in the traditional operation and management model, the compilation of train operation diagram of each line is at the level of independent preparation, without taking into account the dynamic relevance of each line, resulting in the impact of large passenger flows and delays propagated in the network. Faced with this problem, this project analyzes the dynamic correlation mechanism between capacity and demand of each line at the network level. Then this project proposes the concept of "collaborative optimization of train operation plan in urban rail transit network" based on physical network data and train operation diagram data, and is driven by large-scale and high-precision passenger flow data.
Through refinement analysis of the multi-dimensional passenger flow of the network, first, the project proposes a full-day schedule compilation and optimization method to respond to the unbalanced passenger flow in space and time. Then, it proposes a comprehensive optimization and coordination theory for network train operation based on capacity matching degree and train connection. In addition, the project also builds an all-day schedule operation plan maker model (OPM) and an optimization model for network connection scheme (ONC) to form a "Network Operation Decision System" (NODS), which realizes cooperative optimization of the train operation diagrams of all lines in the network. Relevant research has been carried out in many cities in China, to a certain extent, relieving the congestion of large passenger flows in network sections and stations, and improving the travel experience of passengers. So, this project has significant practical value in providing decisions on urban rail transit network operation.

8Shanghai University Of Engineering ScienceIntelligent Decision System for Metro Train Stop Time
With the continuous expansion of the scale of urban rail transit in my country, how to effectively manage the huge passenger flow of urban rail transit and shorten the travel time of passengers has become an important issue to be considered in urban development. At present, the planned stop time of the subway is unreasonable, which greatly affects the continuity of passenger travel and increases the waiting time and transit time of passengers. Therefore, it is urgent to improve the punctuality, short-term and planability of the subway.
Different from the current operating chart, the boarding and landing time is mostly subjective and empirical, which cannot meet the reasonable needs of the driver's standardized operation and the passenger's boarding and landing time. Facing the problem of intelligent decision-making for the precise planned stop time of subway trains, the team comprehensively uses Wi-Fi sniffing technology, video image recognition technology and traffic optimization modeling technology to develop intelligent and precise decision-making models and systems for the planned stop time of subway trains, including Three sub-modules: passenger flow monitoring and identification, planned stop time optimization, and planned/actual stop time assessment. The product of the project has been demonstrated and applied in Shanghai subway operating companies, effectively solving the problem of the mismatch between the actual stop time of the subway train and the planned stop time, not only ensuring the scientificity, rationality, and feasibility of the subway train schedule, but also It can save the purchase cost of subway vehicles and the cost of passenger travel time by tens of millions, which has produced huge social and economic benefits. The system can be extended to conventional public transportation, intercity railway and other public transportation fields, and has broad prospects

12Shanghai Maritime University (SMU)Development of a Secondary Traffic Accident Detection and Early Warning System for Highways
The fully enclosed nature of highways, the fast speed of vehicles as well as other factors make it difficult for highway traffic accidents to be dealt with in time, which is often prone to serious casualties caused by secondary accidents. Our group designed a highway secondary accident warning device with the help of a stm32 microcontroller. This device can be installed on vehicles and help monitor the driving status of vehicles. By collecting accident information from other vehicles, it can remind drivers and passengers of the occurrence of secondary accidents as a result. Teamwork is composed of four subsystems: a data acquisition subsystem, a visualization processing subsystem, an information display subsystem and an information release subsystem. Thanks to the advantages of ZigBee communication system, this device is able to adopt both centralized management and decentralized control mode. Each module is independent of one another, reducing control interference and, at the same time, reaching an organic combination between one aother. With the powerful processing ability of STM32 controller, a variety of data are integrated, analyzed and processed for judging the vehicle state. A high-performance sensor can timely and accurately send data back to the STM32 control center, in which the raw data is analyzed and stored. When an accident occurs, the sensor will quickly make a danger judgement which will soon be transmitted to the surrounding vehicles via the information release subsystem so as to prevent the occurrence of secondary accidents as soon as possible.
13Southwest Jiaotong UniversityResearch and development of railway passenger portrait information system based on big data technology (urban agglomeration)
The research on passenger image information systems for (city cluster) railways was inspired by the successful application of user image technology in the e-commerce sector, airlines and the current dilemmas faced by passenger marketing in the field of railway and intercity railway:
(1) the supply of passenger transport is not adapted to market demand;
(2) the distribution of capacity resources is not adapted to the requirements of transport organisation;
(3) the production organisation model is not adapted to the needs of train operations. The current railway (intercity railway) passenger marketing system is based on traditional report analysis and statistics, which is not sensitive enough to analyse changes in passenger demand, not supportive enough for passenger planning, and not sufficiently utilising the extensive passenger data accumulated The theory of user portrait has formed a set of mature solutions, but the research on passenger portrait information system for railway transportation is still at the initial stage. Therefore, this project's introduction of the user image system into the railway passenger transport sector is an in-depth integration of cutting-edge information technology and the railway industry, as well as a powerful means of adapting to the diversified passenger transport needs,
accurately matching transport supply and demand and shaping the quality of public transport services. The railway passenger image information system research is divided into two stages: the first stage is to develop a railway passenger image information system. The first phase is to develop the railway passenger image information system. In this phase, the deficiencies of the existing passenger marketing system are investigated and analysed, a passenger image labeling system and a high-dimensional heterogeneous incremental data flow clustering algorithm are constructed, an information system analysis platform is built based on big data components such as Hadoop and Spark, and cutting-edge technologies such as big data, artificial intelligence and stream computing are combined to complete the development, testing and maintenance of the system. The second stage is the promotion and application of the railway passenger profile information system. Based on data mining techniques, the system generates statistical reports and carries out visualisation and analysis, thus realising accurate marketing of passenger travel and assisting the management of railway passenger marketing in decision-making. On the basis of this system, secondary development will be carried out to complete passenger flow demand prediction, real-time analysis of travel characteristics, real-time analysis of mobility characteristics between city groups and other functional development. The research team takes care of user privacy and prepares privacy notes.
14Soochow UniversityResearch on Route Choice for Rail Transit Passenger
Under the background of urban rail transit network operation, the one ticket system and seamless transfer mode bring convenience to rail transit passengers, but also bring challenges to operation management. Only analyzing OD data can not grasp the specific travel path and passenger flow distribution law of passengers in the rail transit network, so it is particularly important to grasp the behavior law of passenger route selection in rail transit network.

① The node of rail transit station is divided into several nodes, and the expressions of parking arc and transfer arc are added. On this basis, the topological model of rail transit network is established.

② Through the depth first search algorithm, the reason why the effective path contains unreasonable road sections is found out. A method to determine the redundant road sections based on the sequence of transfer nodes is proposed.

③ Quantitative analysis of rail transit network familiarity, travel time, transfer times, transfer walking distance and congestion degree on passenger route choice.

④ Considering the influence of congestion degree and transfer times in the generalized route cost, the congestion coefficient is redefined to make it more suitable for the actual passenger flow. MSA algorithm is used to solve the problem of passenger flow assignment in rail transit network.

⑤ Python language is used to realize the whole rail transit network path search algorithm and network passenger flow assignment model. The calculation results of Suzhou rail transit show that the research results have good basic value in practical application.

⑥ This paper uses the neural network algorithm to comprehensively consider the distribution results and the existing passenger travel data, and obtains the passenger flow path prediction results based on short-term prediction, which has guiding significance for passenger travel, such as reminding passengers of the current network congestion status and realizing more effective traffic system management.

16Soochow UniversityRail Transit Passenger Flow Estimation System Based on Machine-Vision Regression Integration Model
The section passenger flow statistics of rail transit is the basis of accurate prediction and impact assessment of future rail transit large passenger flow. The existing passenger flow measurement technologies such as infrared sensor and pressure spring have obvious defects in cost control and passenger flow statistics error. This project provides a rail transit section passenger flow estimation scheme based on machine vision and spatial grid, and realizes intelligent passenger flow monitoring with high cost performance. Aiming at the problem of single video data, this project combines the federal learning and integration strategy. We use Fast RCNN, FCHD and Yolov3 algorithm to detect the head features, and completes the rapid detection of passengers in small targets and occlusion scenes. The spatial grid generation method makes up for the deficiency of vision detection ability in remote and occlusion, and realizes the estimation of vehicle passenger flow. The test results show that the federal machine vision detection method can adapt to the light weight and fast passenger flow detection in the rail transit carriage environment, and the passenger flow estimation of the vehicle is similar to the actual operation situation. Compared with the methods of infrared induction, radio frequency and pressure spring, the method of this project does not need to add additional monitoring equipment without reducing the statistical accuracy, which effectively controls the application cost.
17Dalian Maritime UniversityDesign and Optimization of Demand Responsive Transit System Considering ECO-Routing Strategy
The transportation industry is experiencing crisis of oil shortage and serious greenhouse gas emission. Especially, until 2040, road transportation is estimated to account for 43% of total transportation oil demand which will be the largest sector of oil consumption. And then, the produced carbon emission will occupy about 25% of total emission over the world, and turns to be a major source of environmental pollutants. Specially, the eco routing is inspired with a great potential to be effective measure of improving fuel economy and saving the environment in the near term both at the operative and tactical levels. The eco-routing aims at optimizing an environmental path with a minimum consumption of gasoline. To this end, various types of useful guidance was proposed, such as, driver behavior training, intersection management and vehicle longitude trajectory optimization. In recent years, with rapid development of Connected Vehicle (CV) Technology and more new investigations in Driving Navigation Systems, the driving can significantly profit from various types of Connected Vehicle data, likely, traffic state, geometric design (especially about terrain information), signal timing and etc., that would directly raise more conveniences and lay a solid foundation for more advanced eco-routing systems.
However, the applications about eco routing strategy in transit system are quite rare for now. It might be due to the fact that traditional buses run at a fixed-route constrained by the pre-defined schedules. Thus, lack of capability of rerouting dynamically has narrowed the application range in conventional transit system to some extent. Nevertheless, the situation changes when it comes to demand responsive transit (DRT) that is designed to offer flexible and personalized transit services, in which buses will be dispatched with dynamically modified routes and schedules for meeting different types of riding preferences, such as boarding time windows and destinations. The working mechanism of DRT services is naturally assigned with more spaces to be embedded with eco routing system that is expected to offer an optimized environment-friendly routing plan with maximum fuel efficiency and minimum emission.
Note that, different from general traffic, applying eco routing into DRT should be restricted by a series of DRT operational requirements, especially about passengers’ preferences of riding requests, therefore, a fundamental question is further raised under such circumstance: how can we propose the specialized eco routing techniques under the context of DRT operational framework. To our knowledge, the literature remains silent on such significant subject as all of the previous works about DRT design problem concentrate in finding a shortest routing plan considering user preferences while all environmental impacts are neglected, may leading to unnecessary extra fuel consumption and more emissions. In light of the above, and also in order to further specializing the state-of-the-art of eco routing techniques for serving transit system, the present paper contributes to:
 developing a DRT-oriented eco-routing framework in which the module of vehicle dynamics and vehicle emission are integrated into the optimization of velocity profile for DRT services within DRT operational framework;
 minimization of fuel consumption and emission in response to the complicated traffic conditions and different types of road geometric design when design of DRT routing and scheduling plans;
 proposing an efficient solution algorithm for reducing computational burden in preparation for future on-road applications.

25Nantong UniversityYi Tong Chu Xing" -- the core pedestrian skills training system for children based on traffic safety psychology
Yi Tong Chu Xing" system is a training system that uses virtual reality technology, aiming at simulating potential risks when children crossing the street, and develops highly simulated traffic situations to improve children's pedestrian skills.
This system uses unity 3D development tools,3ds Max modeling software and HTC Vive virtual reality helmet equipment to develop a traffic safety training system for children crossing the street, which simulates the typical situation of traffic accidents for children in real life. At the same time, it uses reinforcement, connection and other learning principles to contact targeted training around children's lack of pedestrian skills, so that children can personally experience the dangers in the process of crossing the street, master the correct crossing behavior, and finally improve children's crossing skills.
The work constructs three typical task situations of children crossing the street, including the speed and distance perception situation, the children's sight blocking situation, and the children crossing the street in the presence of others. Considering that the traffic situation without traffic lights is complicated, and children are more likely to have traffic injuries, all scenes are designed as without traffic lights. Three situations are targeted to train children's ability to judge the crossing time, to perceive potential risks and to make decisions on crossing the street, including the training of specific pedestrian behavior norms. Combined with the characteristics of children's psychological development, the system highlights the feedback of training and the transfer-ability of effect.
This work has been tested and tried in primary schools, and has a good training effect. The user's evaluation of the system performance is good.The work was also affirmed by Dr. David C. Schwebel, the scientific consultant of the National Center for Injury Prevention and Control.

Due to the rapid urbanization, population density and growth of the Philippines, this has led to trafic congestion in roads of major cities throughout the country, according to (Boquet, 2013). The reduction of pravate vehicle dependency is a good pathway to achieve sustainable mobility; it leads to the incresing percentage shares of non-motorized modes and public transport modes that contribute to the improvement of traffic flow, energy-saving,mobile emission abatement, and social equity(Rith, Roquel,, 2020)
Having said, this work aims to improve the Philippines' current transportation dilemma, by using transportation models that integrates old modes to newer tranvel transportatio methodologies towards sustainable and modernized mass transportation systems.
The project is able to address issues in mobility by allowing the user to plan in advance their preferred destination routes. Using computing technologies, the system is ale to determine available modes of transportation to and from the selected destination. Other features such as travel queuing, alternative routes determination, and contactless payment are also made available. The designers introduced a portable wifi stand at the terminal to give date connectivity to passanger without mobile date so they can access the full features of the current technology.

Recently, recycled asphalt pavement or reclaimed asphalt pavement (RAP) is increasingly employed as the main source for hot-mix asphalt manufacture. Numbers of past research targeted in evaluating the performance, workability, and constructability of asphalt hot-mix recycling; however, limited numbers of research on road safety aspects have been found. The safety of road and public transport users greatly depend on the frictional characteristics of the road surface. Slippery road surface may cause fatal road accidents to the road and public transport users. Presently, frictional characteristic or skid resistance is conventionally used to identify the current-state level of road safety. The skid resistant of asphalt materials depends on the binder properties, aggregate properties, construction method and quantity, traffic conditions, and climate conditions. Moreover, the skid resistance of pavement surface is degraded or reduce with respected to structural lifetime. According to the beforementioned reasons, the skid resistance of asphalt hot-mix recycling has been studied in this research. The effects of RAP proportions and gradations are also examined. The deterioration of asphalt hot-mix recycling due to traffic is simulated by the accelerated polishing machine. Therefore, the skid resistance of asphalt hot-mix recycling is characterized and compared to those values measured from the conventional hot mix asphalt concrete.

Concrete is the most widely used man-made material in the world and contributes huge amount of CO2. This report aims to develop sustainable concrete from recycled solid waste for transportation engineering. Mechanical and durability properties of concrete with cement replacement of 25% waste glass powder investigated. Previous research shows that glass powder’s pozzolanic reaction is slower and hence takes up to or even longer than 28 days for glass powder concrete’s strength to catch up with ordinary concrete. Hence, the use of silica fume by 5% mass replacement of cement as well as hydrated lime by 5% addition of cement was tested. Since early age strength would be required for on-site concrete casting so that works can proceed, early age strength is one of the important factors to consider for mass use of glass powder incorporated concrete. In terms of durability, alkali-silica reaction expansion tests were also conducted with mortar bars. The effect of glass when used as powder form and how much it results in ASR is also documented to have a check on cracking due to concrete expansion. In addition to testing of the mechanical properties, our team explored the viability of the sample with glass replacement to be used for 3D cementitious printing. This was achieved by testing for the rheological properties of the mix, checking the flowability of the mix with slump flow test and simulated the extrusion of the mix with a syringe to quantify the force required to extrude the mix.
