El Paso, TX, USA and Ciudad Juarez, Mexico form the largest bi-national metropolitan area in the United States and Mexico. Currently, both cities rely on separate public transit bus networks that are not linked and the only cross-border connection is available through three major international bridges opened for cars and pedestrian traffic. In 2017, the City of El Paso adopted the Resilience Strategic Plan to make El Paso smarter. The plan proposes among others the development of Rapid Transit System Corridors in El Paso. This paper presents a high-level proposal how a passenger rail system could be used to complement the existing and future Bus Rapid Transit system as well as local circulator bus system. The proposed rail network is intended for passenger transportation in El Paso, but also beyond into the surrounding region including a cross-border link to Ciudad Juarez, without which the network cannot be considered complete.

The endeavor of suburban transit agencies to improve operation efficiency and transit experience still faces significant challenges due to the long waiting time caused by low service frequency, as well as the lack of connectivity between different transit modes. This work proposes an integrated dynamic transit operation (IDTO) system solution to support enhanced operations of multimodal public transit involving rail rapid transit, bus and on-demand transit. The IDTO system enables the commuter to interact with the transit systems on real-time travel needs and trip options by providing dynamic transit applications including transfer connection protection (T-CONNECT) and dynamic travel management (T-DISP). An IDTO prototype with T-CONNECT capability is developed by implementing a dynamic bus holding control strategy that incorporates dynamic inter-stop trip times and passengers' demand. Field operational test results from real world multi-line bus system and rail transit system indicate that the proposed IDTO can effectively improve the success rate of transfers and reduce the commuters' waiting time during transfer.

A rational and efficient tool is needed for the scheduling of public transport bus services that will satisfy the needs of passengers for different service time requirements. An intelligent urban bus system should not only be able to reduce carbon emissions and traffic congestion, but also to improve transport services. A model is proposed which computes Shapley values for seventeen different time periods in one day for a bus route. A fair allocation of buses based on the Shapley value is made which entails the minimum amount of deployment cost. This study applies data for the rapid transit bus system in the city of Xiamen in China to verify the Shapley value model. The simulation results show that management can easily use this framework to quantitatively allocate buses along routes within the seventeen time periods in one day and that the proposed approach is more efficient than current bus scheduling methods.

This paper deals on the featured impact of the spread of Bus Rapid Transit (BRT) technology in the Italian distribution networks framework. Because of its particular charging method, quick at stops and slower at terminals, an investigation of its effects on the electricity network is needed. For the purpose a methodology is firstly defined and proposed, and then a test case reproducing a realistic Italian scenario is implemented. Results of simulation tests about distribution network performances under charging conditions are commented, bringing overall considerations about the feasibility of implementation of this solution.

This paper presents the intruder detection system for rapid transit using CCTV surveillance based on the histogram shapes. In this paper, researchers proposed intruder detection algorithm of yellow line located on the ground next to rapid transit railway for preventing passengers from any harmful train incidents by using CCTV surveillance system based histogram shape that is incredibly convenient technique for image analysis. The histogram shapes of trespass and non-trespass are different. Therefore, it can be used to alarm as a warning system to the passengers who invade the yellow line. The good advantages of the histogram shapes method are; flexibility in use and stability in light changing. This research is suitable for CCTV surveillance system used in observation mode for intruder detection. The system can be worked both on real time and offline mode. The experimental results show the error of the system that is less than 5%.

This research is mainly investigating into the power variations between non-regenerative braking power mode and the regenerative braking power mode of the Electrical Multiple Units (EMU) which are used in Taipei Rapid Transit Systems (TRTS) Nangang, Banqiao and Tucheng lines. It also aims to find the optimal usage of the regenerative braking power, not only providing a reasonable planning of the substation capacity for construction at the initial stage in order to avoid possible waste on investment, but also effectively reducing loadings of the electric power facilities and the related power expenditure at the stage of operation. Moreover, it is expected that other metro authorities in our country will therefore pay more attention to the EMU's regenerative power utilization, and eventually apply it to the planning and design of the EMU regenerative power for all the railway systems.

The paper mixes extension theory and gray clustering method, and constructs the evaluation system of the bus rapid transit system based on gray extension matter-element model, using the evaluation grade of bus rapid transit system, the indicator evaluation standard and the basic characteristics value as the matter elements, applying gray clustering method to calculate the weight and the correlation degree. The example calculation shows that the model can not only reflect the overall development level of the rapid transit system comprehensively, but also identify the relative difference between the specific indicators and the standard values.

Moreover, mitigating the disturbance to normal service of existing system during the extension is discussed; the activities being taken to ensure the success of the extending and upgrading project are presented.

A successful power projection campaign may require operations through littoral defenses, including mines. Mines are the most prolific weapons available to other nations intent on inhibiting US Naval forces' ability to project power from the sea. Therefore, mine countermeasures (MCM) is integral to the overall power projection campaign. Countering the mine threat is critical to naval forces ability to effectively shape and dominate the battlespace. Future operations will require rapid transit through the littoral regions. The success and effectiveness of any naval operation depends on the capabilities of the equipment, the environment, and detailed knowledge of the threat. New capabilities need to be developed to use the environment to a tactical advantage. This paper describes how the environment is being used and should be used in support of MCM in the littoral regions.

This paper presents an overview of the DC traction scheme utilised within the Singapore RTS as well as the operational scenarios that is taken into consideration in developing the DC traction scheme

Our MRT system is highly dependent on electric power to meet the public transportation needs. In Singapore, our dependence on electricity has not been taken for granted and it has always been a long-term objective to be energy efficient not only in terms of operational cost but also due to environmental responsibility. In Singapore, in order to move reliably millions of passengers day in day out, the electric bill can be pretty hefty, in the order of millions of dollars. This paper highlights the various energy conservation measures currently adopted for our Rapid Transit System as well as the some of the ongoing efforts in seeking out alternative energy conservation measures

For many electromechanical systems, early fault detection, is invaluable as pre-emptive maintenance can result in tremendous savings for the operator, instead of dealing with the faults when they occur. In this work, we investigate the use of pattern recognition and classification techniques for fault diagnosis in rapid transit vehicles. Operational data are processed using the principal components analysis method to reduce their dimensionality, and are then clustered and classified into identifiable behaviors or classes. Faulty data are examined and compared to normal behaviors. This proof-of-concept demonstration shows promising results to warrant further investigation in the use of pattern recognition techniques in fault diagnosis for rapid transit vehicles.

A steel wheel/rail technology based on the Chicago Transit Authority's rapid transit system has been postulated as a possible replacement for the existing VAL rubber tire on the O'Hare airport transport system (OATS). The replacement technology is dubbed the Chicago O'Hare rail network, or CORN. Replacement of VAL may be justified when the current VAL system reaches a point of needing a major overhaul and/or when major extensions are planned for the system.

Several forms of motive power are described that could offer much lower implementation costs for suburban rail rapid transit. The same concepts could apply to suburban electrified commuter railroads where electric operation is mandatory on critical center city terminal portions of a system. The proposed alternatives for heavy (i.e., high platform) rapid transit ought to have costs on the order of those usually associated with light rail transit while still providing the spaciousness and comfort associated with suburban heavy rail rapid transit. The unconventional motive power units described are intended to allow extension of existing (or proposed) electric rail transit into distant suburbs using nonelectrified railroad tract that may be abandoned or occasionally used by a freight train. >

In connection with the second phase of the Advanced Group Rapid Transit (AGRT) project sponsored by UMTA, General Railway Signal Company has refined the design of a control system for a high-performance (3-second headway) Personal Rapid Transit (PRT) system. The control system utilizes a variable length moving block control algorithm, and features a combination of multiple wayside and vehicle-borne computers that are connected by a wide bandwidth data link to achieve the desired performance. In this phase of the project, a major effort was directed toward developing a highly detailed simulation of the entire control system. This simulation was undertaken to verify that the deployed system would meet previously defined performance specifications. This paper will discuss the implementation of the simulation and describe its use in verifying system operation at both macroscopic and microscopic levels. Examples of microscopic operations studied include effects of communication delays and errors on system operation and scheduling of different processes on the same computer. Examples of macroscopic operations studied include the operation of several vehicles merging at a junction, the response of several vehicles in a string during normal station stopping maneuvers, and responses to various failures that require emergency action.

The continuing quest for improved service and operational efficiency in rail transit systems has led to the use of newer designs in signalling and propulsion subsystems. Although these new designs have produced resource savings in these energy and cost-conscious times, they have the potential for generating electro-magnetic interference problems -- problems that also must be dealt with in a cost-effective manner.

The main components of two alternative flow-coordinated strategies upon which an overall vehicle management problem might be based, are outlined. A fundamentally new approach to the vehicle management problem is presented which takes into account station capacity constraints and which is potentially applicable to large, topologically complicated systems operated at high vehicle density levels.

For many years, GRS has supplied control systems for conventional rail transit. Headways for these systems range from minutes or hours to as low as 75 seconds, In the last few years, the company has supplied control systems for people-mover applications in which minimum headways of 10 to 20 seconds have been achieved. The 75-second design headway of a model Conventional Rail Transit (CRT) system is compared with the 18-second design headway of a model Automated Guideway Transit (AGT) system from the viewpoint of potential for reduced CRT headway. It is shown that the major CRT factors responsible for this headway difference are on-line stations, train length and Safe Braking Distance. These factors are evaluated and discussed. It is concluded that a large increase in CRT track capacity should not be expected from the transfer of control technology from AGT.
