This webinar is being led by Leidos, the Traffic Signal Change and Clearance Interval Transportation Pooled Fund Study Phase II contractor, and is supported by the Federal Highway Administration and ITE.
Webinar Description:
This webinar presents the proposed research and data collection methodology for the Traffic Signal Change and Clearance Interval Transportation Pooled Fund Study (TPFS) Phase II, led by the Federal Highway Administration (FHWA). Phase II of this TPFS seeks to improve the understanding of key factors used to determine appropriate selection of traffic signal change and clearance intervals (CCIs) and assess CCI safety and operational impacts. The TPFS completed Phase I which synthesized the knowledge on traffic signal CCIs, identified research gaps, developed a research plan, and evaluated potential data collection alternatives (see ITE On-Demand Webinar An Update on Traffic Signal Change and Clearance Intervals which includes information from Phase 1).
The Phase II study uses the Phase I synthesis report as a foundation but conducts additional review to identify potential information gaps and synergies the Phase I report might have overlooked. This webinar presents a methodologically approach outlining the site selection, data collection plans, and potential analysis for achieving the Phase II objectives. During the webinar, the team will discuss how their approach incorporated into the proposed studies concepts for efficient data collection, and integrated the insights gained from technical panel meetings, their feedback, and the benchmarking survey results into the research plan.
Learning Objectives:
- Describe the Traffic Signal Change and Clearance Interval TPFS project (e.g., objectives, schedule, deliverables).
- Recognize key research questions to address in this project (e.g., driver behaviors for making stop-go decisions, driver behaviors for turning vehicles at the onset of a yellow signal and underlying assumptions for the extended kinematic equation, impacts of long yellow interval times on driver behavior and intersection operations).
- Understand preliminary model development plans in this project (e.g., safety risk function, probability of stopping curves, change in safety and mobility measures associated with changes to CCI durations).
- Identify challenges of the research work plan (e.g., data types to address key research questions; data collection methods, sites, and schedule/budget constraints).
