Available in PDF, EPUB and Kindle. Book excerpt: Although signal priority has proven to be an effective tool for reducing delays to buses, this technique is not always beneficial to the overall traffic network. Providing priority for transit vehicles along a corridor with a large number of transit vehicles can cause a coordinated network to be out of step resulting in an overall increase in delay. Bus signal priority also has the disadvantage of penalizing the cross-street traffic when high transit volumes exist at the corridor. The objectives of the research described in this report is to assess the impacts of and the implementation issues associated with the use of bus signal priority in New Jersey and to assess the benefit and costs of signal priority.

Download or read book Evaluation of Service Reliability Impacts of Traffic Signal Priority Strategies for Bus Transit written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent progress in technology has facilitated the design, testing, and deployment of traffic signal priority strategies for transit buses. However, a clear consensus has not emerged regarding the evaluation of these strategies. Each agency implementing these strategies can have differing goals, and there are often conflicting issues, needs, and concerns among the various stakeholders. This research attempts to assist in the evaluation of such strategies by presenting an evaluation framework and plan that provides a systematic method to assess potential impacts. The results of the research include the development of specific measures corresponding to particular objectives, with descriptions to facilitate their use by agencies evaluating traffic signal priority. The use of this framework and plan is illustrated on the Columbia Pike corridor in Arlington, Virginia with the use of the INTEGRATION simulation package. In building upon prior efforts on this corridor, this work presents a method of simulating conditional granting of priority to late buses in an attempt to investigate the impacts of priority on service reliability. Using the measures developed in this research, statistically significant improvements of 3.2% were found for bus service reliability and 0.9% for bus efficiency, while negative other traffic-related impacts were found in the form of increases in overall delay to the corridor of 1.0% on a vehicle basis or 0.6% on a person basis.

Book Synopsis Evaluation of Transit Signal Priority Effectiveness Using Automatic Vehicle Location Data by : Carl Andrew Sundstrom
Download or read book Evaluation of Transit Signal Priority Effectiveness Using Automatic Vehicle Location Data written by Carl Andrew Sundstrom and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transit Signal Priority (TSP) is an operational strategy that can speed the movement of in-service transit vehicles (typically bus, light rail, or streetcar) through traffic signals. By reducing control delay at signalized intersections, TSP can improve schedule adherence and travel time efficiency while minimizing impacts to normal traffic operations. These benefits improve the quality of service thereby making it more attractive to choice riders. A TSP system can also allow for fewer buses on the same due to travel time reductions and increased reliability, thus reducing transit operating costs. Much of the previous research on TSP has focused on signal control strategies and bus stop placement with little of it analyzing the effectiveness of the system using actual data. This study aims to evaluate the effectiveness of the system using a bus route corridor in Portland, Oregon through real-time Automatic Vehicle Locator data. Key measures that TSP is promoted to improve are evaluated, including travel time, schedule adherence and variability. The TSP system on data was collected for two weeks and is compared to an adjacent two weeks of bus data with the TSP system turned off such that there is no skewing of data due to changes in traffic volumes or transit ridership. This research has shown, that on certain corridors there may be little to no benefit towards TSP implementation and may possibly provide some disbenefit. The direct comparison for TSP on and off scenarios completed for this research yielded no significant differences in reduction in travel time or schedule adherence performance. An additional interesting result was that the standard deviation of the results did not have any specific tendencies with the TSP on or off. Based on these findings, recommendations are made to increase the effectiveness of the system.
Book Synopsis Transit Signal Priority Evaluation by Micro-Simulation by : Faisal Mahmud
Download or read book Transit Signal Priority Evaluation by Micro-Simulation written by Faisal Mahmud and published by LAP Lambert Academic Publishing. This book was released on 2011-03 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transit Signal Priority is an operational strategy that eases the movement of transit vehicles such as buses, light rail or streetcars, through traffic-signal controlled intersections. The benefits of TSP operations include better schedule adherence and improved transit travel times with minimal impact to normal traffic operations. In this book, a portion of the new Tide Light Rail Transit (LRT) system in Norfolk, Virginia, USA is modeled and evaluated. In order to model and evaluate the TSP operations, a micro-simulation model for the network is created in VISSIM. By using the Ring Barrier Controller (RBC) emulator within VISSIM, the control logic for TSP and No TSP scenarios is created.The analysis and context of the book is helpful to the professionals and students, especially those in the field of urban planning and transportation engineering, or anyone else who may be considering utilizing TSP logic for learning and research efforts. As the book contains in detail experimental results analyses as well as real life field scenario implementation, it will be a drafting tool to gaining knowledge about transit signal priority.

This book was released on 2014 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research demonstrated the effectiveness of Transit Signal Priority (TSP) in improving bus corridor travel time in a simulated environment using real world data. TSP is a technology that provides preferential treatment to buses at signalized intersections. By considering different scenarios of activating bus signal priority when a bus is 3 or 5 minutes behind schedule, it was demonstrated that bus travel times improved significantly while there is little effect on delays for crossing street traffic. The case of providing signal priority for buses unconditionally resulted in significant crossing street delays for some signalized intersections with only minor improvement to bus travel time over both scenarios of Conditional priority. Evaluation was conducted by using micro-simulation and statistical analysis to compare Unconditional and Conditional TSP with the No TSP scenario. This evaluation looked at performance metrics (for buses and all vehicles) including average speed profiles, average travel times, average number of stops, and crossing street delay. Different Conditional TSP scenarios of activating TSP when a bus is 3 or 5 minutes behind schedule were considered. The simulation demonstrated that Conditional TSP significantly improved bus travel times with little effect on crossing street delays. The results also showed that utilizing TSP technology reduced the environmental emissions in the I-Drive corridor. Furthermore, field data was used to calculate actual passenger travel time savings and benefit cost ratio (7.92) that resulted from implementing conditional TSP. Conditional TSP 3 minutes behind schedule was determined to be the most beneficial and practical TSP scenario for real world implementation at both the corridor and regional levels.
