ABSTRACT (Maximum 200 words) This report presents the results of a research project that addresses Transit Signal Priority (TSP) deployment issues. The report reviews National Transportation Communications for ITS Protocol (NTCIP) 1211 Signal Control and Prioritization (SCP) standards, defines five SCP scenarios, and describes how the SCP scenarios can be applied differently based on TSP priority and operating policies. The report provides an overview of a number of TSP systems, including centralized TSP, two discrete TSP systems based on loop detection and Global Positioning System (GPS) technologies, and an Adaptive Transit Signal Priority (ATSP) system. A comparison of the different TSP deployments, and guidance on the necessary infrastructure required to implement these TSP systems, are provided. The report also discusses TSP evaluation methodologies, including recommended measures of effectiveness (MOE’s) and data required for performing a quantitative assessment. Evaluations of a number of TSP deployment sites are documented to demonstrate how the benefits of TSP to transit and the impacts of TSP to traffic operations are assessed using the recommended approaches. Finally, the report provides guidance on TSP planning and analysis methods, such as simulation and regional modeling tools. 14. SUBJECT TERMS 15.

Based on a situation of the variability of traffic composition, the phase clearance reliability (PCR) value of each phase and traffic composition ratio is introduced to reflect the traffic condition at intersection. /en, a bus signal priority optimization model is proposed with the purpose of the maximum of the total vehicular departure as the optimization goal. In order to obtain the optimal solution, an improved algorithm is designed by introducing the PCR value search strategy. Finally, two cases’ study is exhibited to demonstrate the reasonability of the model, theory, and algorithm. /e result shows that the model can not only clear the queue under the condition of continuous dynamic traffic flow but also reduce the vehicle queuing and passenger delay. 1. Introduction the development of intelligent public transport systems is essential to improve the level of public transport service and /e acceleration of urbanization and the increasing urban operational efficiency.

  • Transit Performance Evaluation at Signalized Intersections of Bus Rapid Transit Corridors
    Transit Performance Evaluation at Signalized Intersections of Bus Rapid Transit Corridors Robel Desta1 a, Tewodros Dubale2 and János Tóth1 1Department of Transport Technology and Economics, Faculty of Transportation Engineering and Vehicle Engineering, Budapest University of Technology and Economics, Muegyetem rkp. 3, 1111 Budapest, Hungary 2Department of Civil Engineering, Institute of Technology, Hawassa University, P.O. Box 1528, Hawassa, Ethiopia Keywords: Bus Rapid Transit, Delay, ITS, PTV VISSIM, Transit Signal Priority. Abstract: Bus Rapid Transit (BRT) is one of the mass transportation solutions consisting of infrastructures integrating dedicated bus lanes and smart operational service with different ITS technologies like Transit Signal Priority (TSP). Delay at an intersection is among the major factors for poor transit performance. This study examines the performance of buses at intersections of BRT corridors, which are privileged with Signal Priority on the dedicated lane. Simulation models were developed for the selected intersection together with the real-time calibration and validation. Statistical comparisons were conducted to test the alternative scenarios aimed at visualizing the deployment advantages. TSP options were evaluated by using PTV VISSIM with VisVAP add-on simulation tool. Alternative scenarios with and without TSP were tested to measure the performance of BRT buses along with impact assessment on the general traffic. TSP reduces travel time and control delay, improves travel speed and the results depicted a reduction in average passenger delay by 10–20%. The improvement on travel speed at an intersection of BRT vehicles were determined to be 6–8%. Prioritizing buses has diminutive impact on the general traffic, nonetheless, it is the easiest way of improving transit performance.

COST is supported by the EU RTD Fram ew ork program m e ESF provides the COST Office through an EC contract. Forew ord This publication is supported by COST COST- the acronym for European COoperation in Science and Technology- is the oldest and widest European intergovernm ental network for cooperation in research. Established by the Ministerial Conference in N ovem ber 1971, COST is presently used by the scientific com m unities of 35 European countries to cooperate in com m on research projects supported by national funds. The funds provided by COST - less than 1% of the total value of the projects - support the COST cooperation networks (COST Actions) through which, with EUR 30 million per year, more than 30 000 European scientists are involved in research having a total value which exceeds EUR 2 billion per year. This is the financial worth of the European added value which COST achieves. A "bottom up approach" (the initiative of launching a COST Action com es from the European scientists them - selves), "à la carte participation" (only countries interested in the Action participate), "equality of access" (par- ticipation is open also to the scientific com m unities of countries not belonging to the European U nion) and "flexible structure" (easy implem entation and light m anagem ent of the research initiatives) are the main charac- teristics of COST.

    Transit Capacity and Quality of Service Manual—2nd Edition PART 8 GLOSSARY This part of the manual presents definitions for the various transit terms discussed and referenced in the manual. Other important terms related to transit planning and operations are included so that this glossary can serve as a readily accessible and easily updated resource for transit applications beyond the evaluation of transit capacity and quality of service. As a result, this glossary includes local definitions and local terminology, even when these may be inconsistent with formal usage in the manual. Many systems have their own specific, historically derived, terminology: a motorman and guard on one system can be an operator and conductor on another. Modal definitions can be confusing. What is clearly light rail by definition may be termed streetcar, semi-metro, or rapid transit in a specific city. It is recommended that in these cases local usage should prevail.

  • Bus Infrastructure Design Guidelines Is Offered As a Guide to Transit Infrastructure Design Best Practices, Rather Than As a Set of Strict Design Standards
    Revision 2018.01 (September 2018) USING THIS GUIDE The Bus Infrastructure Design Guidelines is offered as a guide to transit infrastructure design best practices, rather than as a set of strict design standards. Design matters requiring the approval of TransLink/CMBC will continue to be reviewed in previous manner. Municipal and provincial road design standards will continue to be applied. The design parameters and criteria presented in this Guide are suitable for typical applications and will provide operational efficiency, safety and customer comfort. As every project is different with unique site context, Designers should consider site specific context and recommend appropriate design solutions on a case by case basis. For new projects that have specific considerations and/or constraints that may lead to designs deviating from the guidelines, Designers should provide rationale to support any deviations and consult with TransLink at the onset of a project to verify the assumptions and criteria to be followed. This Guide is a living document. As technology, operational practice and customer expectation evolve, the document will be updated as needed. The information presented in the current version represents the best information available at the time of writing. Bus Infrastructure Design Guidelines SOP: Bus Infrastructure Design Guidelines SOP # INM-002 (Rev 01) TransLink Infrastructure Program Management Department – Transportation Owner Engineering Group The purpose of this Standard Operating Procedure is to provide guidance on making updates and changes to TransLink’s Bus Infrastructure Design Guidelines (“BIDG”) following an update to the previous 2013 document. Purpose of The BIDG provides guidance on design practices to accommodate buses and the SOP passengers, and promote safe and efficient bus operations.

Abstract Effectiveness of Bus Signal Priority (BSP) study evaluates BSP’s impact on traffic operations. The goal was to examine how different situations, such as the level of congestion, placement of bus stops, presence of express bus service, and number of transit vehicles on route, require different techniques of BSP such as real-time or fixed-time based control. Those techniques also utilize a variety of different control strategies such as phase suppression, synchronization, compensation, and green recall. In order to guide transportation agencies in this decision-making process, a framework for an ideal bus priority system was developed. Based upon that information, the “Pre-Implementation Checklist” was designed.
