Guidebook for Deploying Zero-Emission Transit Buses
Report Number: R-219
Publication Date: 6/19/2020
The zero‐emission bus (ZEB) market, including Battery Electric Buses and Fuel Cell Electric Buses, has seen significant growth in recent years. ZEBs do not rely on fossil fuels for operation and have zero harmful tailpipe emissions, improving local air quality. The increase in market interest has also helped decrease product pricing.
This pre-publication draft report is designed to provide transit agencies with information on current best practices for ZEB deployments and lessons learned from previous deployments, industry experts, and available industry resources.
Transit Signal Priority: Current State of the Practice
Report Number: S-149
Publication Date: 5/18/2020
Public transit buses face many operational challenges—especially when operating on the same streets and roads as other vehicles. Buses can be slowed by traffic congestion and get repeatedly caught at traffic lights, slowing buses down and delaying both passengers on board and passengers waiting at stops farther along the route.
This report documents the current practice of TSP, which is an important tool that increases bus speeds and reliability, thereby improving transit system efficiency and effectiveness.
Twenty-eight (61%) of the 46 surveyed transit agencies had active TSP deployments, and 13 transit agencies (28%) either are in predeployment testing or have plans to pursue TSP in the future.
Development of Transactional Data Specifications for Demand-Responsive Transportation
Report Number: R-210
Publication Date: 5/04/2020
Demand-responsive transportation (DRT) can produce benefits — fewer empty seats, lower cost per passenger, less delay for customers — to both passengers and transportation service providers, particularly the public and private nonprofit agencies that finance DRT services with public funds.
This report presents a transactional data specification for DRT to facilitate interactions among the software systems that manage these services.
A validator software tool that verifies data messages generated by a software system is available as part of the project.
Business Models for Mobile Fare Apps
Report Number: S-148
Publication Date: 04/29/2019
Five different business models for mobile fare payment apps are examined, as the world of apps used by transit agencies in the United States and Canada continues to steadily grow.
This report documents current practices and experiences of transit agencies that offer mobile fare payment applications to transit riders. It also includes case examples from six cities: Santa Monica, Denver, Austin, Chicago, Dallas, and Ontario, Canada.
Stray Current Control of Direct Current-Powered Rail Transit Systems: A Guidebook
Report Number: R-212
Publication Date: 4/03/2020
Stray current and stray current–induced corrosion remain concerns among transit agencies, electrolysis committees, utility owners, providers, and electric railway carriers across the globe. It is easier to implement stray current isolation, mitigation, and collection options on a newer transit system with proper foresight and planning by following the logical sequence of the design process than to maintain a stringent maintenance and testing regime on an older system.
This report allows transit agencies, design, and maintenance practitioners to influence new system construction, extensions, and maintenance and operation of existing systems.
Improving the Safety and Sustainability of Stray Current Control of DC-Powered Rail Transit Systems (PowerPoint slide deck) highlights the research review and guidebook development.
Transit Security Preparedness
Report Number: S-146
Publication Date: 4/01/2020
Sixty percent of the transit-industry practitioners surveyed rate their transit agency’s efforts to address their major security challenges as somewhat or very successful. However, only 25 percent say they have implemented any security-risk-reduction program that they consider to be exceptional or exemplary.
This report identifies current practices transit systems can use to enhance their security measures and to identify opportunities to apply security technology applications used in other industries to the transit environment.
One size does not fit all in the context of transit security. However, there are common themes in all effective security preparedness approaches.
