Safety effects of Green-Man Countdown Device (GMCD) at signalized pedestrian crosswalks are evaluated.
Pedestrian behavior at GMCD and non-GMCD crosswalks is observed and analyzed.
A microsimulation model is developed based on field observations to estimate safety performance.
Simulation outputs allow analysts to assess the impacts of GMCD at various conditions with different geometric layout, traffic and pedestrian volumes, and the green time.
According to simulation results, it is found that the safety impact of GMCD is affected by traffic condition as well as different time duration within green-man signal phase.
In general, GMCD increases average walking velocity, especially during the last few seconds.
The installation of GMCD improves safety performance generally, especially at more crowded crossings.
Conflict severity is increased during last 10 s after GMCD installation.
Findings from this study suggest that the current practice, which is to install GMCD at more crowded crosswalks or near the school zone, is effective.
Moreover, at crosswalks with GMCD, longer all red signal phase is suggested to improve pedestrian safety during intergreen period.
