Compared with the traditional subway lines, the automatic operation of subway not only has great changes in the functions of vehicles and equipment, but also has different requirements for the quality and business ability of front-line operation staff. In December 2019, the white paper "guidelines for operation requirements of fully automatic operation system of urban rail transit" was issued, which clearly classified the operation of train operators into three categories: Traffic Dispatching in control center, comprehensive management dispatching, on-site operation personnel and on-board duty personnel. With the development of automatic operation system technology, the traditional bus driver, station attendant and other posts will gradually merge and be replaced by the on-site operation personnel, such as station and train comprehensive post. The research on the competency model of station and train comprehensive post can help each metro operation unit to clarify the required ability and quality of its post personnel, scientifically guide the recruitment and selection of on-site operators, the construction of training system and personnel management, and ensure the smooth operation of fully automatic metro lines. This paper attempts to use the methods of job analysis, interview survey, questionnaire survey and data analysis to construct the competency model of comprehensive post of metro station and train under automatic operation system, including four dimensions of professional ability, professional knowledge, basic quality and personality characteristics, with a total of more than 20 characteristic indexes, providing guidance for the preparation and operation management of fully automatic operation subway.

|With the development of urban rail transit, the shortage of equipment and maintenance professionals is increasing, and the traditional track inspection mode relying on manual inspection is gradually showing many drawbacks:
1、 The short window of time for urban rail transit is only 3 hours, and the manual inspection in two-person teams can only complete about 7 km of line work per window point, which is inefficiency and high costs.
2、 manual inspection has a high rate of missed inspection, the data cannot form a quantitative data format, cannot be continuous track deterioration state analysis and prediction, many track failure cannot be timely found and thus develop into a major hidden danger affecting operational safety.
To this end, this project investigates a 3D vision-based 2D image + 3D shape visual measurement technology for intelligent inspection robots to measure the visibility status of track equipment, generate a multi-dimensional quantitative data lake based on the measurement results, and use the data lake to carry out quantitative prediction of track deterioration trends.

|26||Zhengzhou Tiamaes Technology Co.,Ltd||Intelligent Chain Scheduling Technology based on tabu search
and dynamic programming algorithm
|Efficient bus scheduling is an important part in public transportation operation management to solve the problem of urban traffic congestion. For nearly half a century, most of Chinese public transportation companies have adopted a driver-vehicle binding scheduling mode. Driver-vehicle binding means that one driver can only run one vehicle. The advantages of this model are convenient for business management and division of responsibilities, but the disadvantages are also quite obvious. The main reasons are that the driver’s labor efficiency is low and the resources required by the public bus company are also relatively large. Intelligent chain scheduling technology is mainly used to solve the Single Deport-Single Line-Vehicle Scheduling Problem (SD-SL-VSP) and Single Deport-Multi Line-Vehicle Scheduling Problem (SD-ML-VSP). This technology breaks the original working mode of order scheduling of public transportation companies and adopts a more efficient scheduling strategy, that is, the vehicles returning to the home area first are arranged at the nearest departure point to perform the next tasks. At the same time, this technology is mainly aimed at the domestic bus driver scheduling problem under the "driver-vehicle binding" mode. At the same time, considering the cost of vehicles and drivers, the scientific model algorithm, namely the greedy tabu search algorithm, is used to find the smallest number of vehicles and meet the scheduling plan. This product can balance the relationship between the vehicle and the driver on the premise of saving resources to a certain extent, that is, reducing the resources of the enterprise on the basis of effectively improving the labor efficiency of the driver.|

Power is supplied to trains from contact lines on the ground through the pantographs mounted on trains. Therefore, it is necessary to adopt a contact line system that will limit contact loss within the allowable limits for inverters. In addition, high-speed railways of China tend to be constructed in tunnel sections in recent years. When compared with catenary systems, rigid conductor line systems feature a simple structure and easy maintenance. It also saves tunnel Construction costs. Since conventional rigid conductor lines do not have elasticity against pantographs in current collection. However, the current collecting performance depends on its pantograph compliance characteristics and the unevenness of its contact surface. This makes it difficult to cope with train operation over 160 km/h. To use rigid conductor line systems for train operation over 160 km/h, therefore, we have developed a new rigid conductor line. Running tests have proved that the new rigid conductor line ensures current collection up to 200 km/h and is applicable to train operation even at higher speed due to its superb performance of current collection.|
|33||Digital Rapid Transit (Shanghai) Transportation Technology Co., Ltd||Digital-Rail Rapid Transit System|
|Digital-rail Rapid Transit System is a new type of orbital, digital and intellectualized medium-capacity rail transit system, which adopts modern tram operation and control mode, with magnetic tag as virtual (digital) track and self-guided digital track rubber tyred tram as carrier. DRT replaces the physical steel rails in traditional rail transport with digital ones, supports rubber tyred tram with constraints from digital tracks and thus realizing the self-guided driving. Additionally, digitalized coding is formed through the orderly arrangement of magnetic tags (magnetic nails), the basic unit of digital track, and provides the tram with functions of accurate positioning in centimeter level, scene foresight, electronic map, electronic switch, and other functions. The main components of Digital-rail Rapid Transit System includes: ①digital track; ②rubber-tyred tram with low floor and new energy digital track; ③virtual-rail rubber-tyred tram operation control and dispatch system, based on digital track, and other subsystems, involving digital turnout control, vehicle control, dispatch management, depot dispatch, etc.,; ④wiring matched with digital track, digital turnout, station and parking lots; ⑤dispatch operation schedule system, signal priority system, integrated passenger service system, communication system, power supply system, safety and technical defense, automatic fare collection, digital rail vehicle maintenance and management system, etc.Functions of precise operation control, safety defense, auxiliary and quasi automatic driving and operation monitoring, for example, can be implemented by the comprehensive combination of different supporting technologies specifically for digital track, like autonomous driving and intelligent sensing. Meanwhile, the system integrates the features of new infrastructure such as vehicle networking and 5G communication and guarantees a reliable and innovative medium-capacity transit system transportation scheme for urban public transportation system.|
