77 A P P E N D I X A Survey Instrument Q1 TCRP Synthesis SA-47: Bus Transit Signal Priority (TSP) Current State of the Practice The Texas A&M Transportation Institute (TTI) is leading research for the Transit Cooperative Research Program (TCRP) on bus transit signal prioritization. The research, TCRP Synthesis SA-47: Bus Transit Signal Priority (TSP)—Current State of the Practice, will document transit systems’ current use of TSP and will provide an overview of: - TSP strategies and parameters, - The resulting benefits from TSP, and - An assessment of to what extent the disparity in benefits realized are driven by strategy and parameter choices. This survey is the first step in the research project and needs completed by March 1, 2019. This survey will take approximately 15–20 minutes to complete. Advancing from screen to screen saves your responses. You may exit the survey and return to finish later. You may also forward the survey URL to other colleagues to help you provide the information requested in this survey. Please note that when you or your colleague reenter the survey, the survey will open on the last question you viewed. This survey will ask questions about your agency’s bus TSP deployments, including, but not limited to, the following: - Business rules - Specific business rule parameters - System configuration(s) - Installation costs - Benefits The information you provide will be synthesized with information collected from other transit professionals. Your answers will be confidential to the extent permitted or required by law. Your participation is greatly appreciated. If you have questions, concerns or complaints regarding this study, you may contact Chris Simek at 512-407-1153, c-simek@tti.tamu.edu. You must be at least 18 to participate in the survey.

82 Transit Signal Priority: Current State of the Practice Q23 Definitions and Specifying Deployment Groups The next several questions will collect some details about the manner in which your transit agency utilizes bus TSP. In order to maintain consistency, it is necessary to define some terms that will be presented in the survey. Configuration: the functional design of the TSP system’s hardware and software, including how TSP system components and modules work together. An example TSP system configuration could be that buses request TSP at intersections using an infrared transmitter. Business rules: the collection of rules and decision logic that determine whether TSP is requested and whether TSP is granted. There are many types of business rules: bus eligibility, intersection eligibility, priority eligibility and priority type. Parameters: the specific values associated with individual business rules. For example, the business rule may be that only late buses request priority. The parameter is HOW late (in seconds or minutes behind schedule). Deployment group: a collection of bus routes, buses, and intersections that share a common TSP system and the same or similar configuration, business rules, and parameters. A TSP deployment group could be implemented across multiple corridors or geographic areas or at different times. What defines a deployment group is how the system works and what business rules and parameters are in place, not necessarily where and when TSP was deployed. The concept of a deployment group is necessary in this survey, because some transit agencies have implemented different bus TSP systems or have adopted different sets of business rules in different corridors. Q24 Please think about how your agency has deployed bus TSP. How many deployment groups does your agency currently have? Remember, a deployment group is a collection of bus routes, buses, and intersections that share a common TSP system and the same or similar configuration, business rules, and parameters. 1 (1) 2 (2) 3 or more (3) Display This Question: If Please think about how your agency has deployed bus TSP.

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.

The TRB Transit Cooperative Research Program's TCRP Synthesis 149: Transit Signal Priority: Current State of the Practice 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.
