Gap study
Vehicle interval analysis for crossing feasibility decisions.
Services
GAP Study
GAP studies analyze time differences between vehicles in a traffic stream to understand available crossing and merge opportunities. Findings support pedestrian-safety evaluation and informed decisions for intersection design, signalization, and traffic-control strategy.
Service objective
Determine whether available traffic gaps support safe crossing and turning maneuvers under observed field conditions.
Tooling stack
Manual observation teams
Camera and radar-assisted gap capture
Timestamp interval logs
Gap-distribution analysis templates
Process sequence
Step 01
Objective and site definition
Define crossing or intersection questions and select the roadway segment where gaps will be measured.
Step 02
Gap data capture
Record consecutive vehicle positions and time intervals using manual, automated, or hybrid collection.
Step 03
Stream behavior analysis
Analyze gap distributions under different traffic states to identify feasible crossing opportunities.
Step 04
Design and control guidance
Translate findings into recommendations for crossing treatments and intersection control strategy.
