The duration of the pedestrian phase, seen in Figure 1 (Walk interval + Clearance interval), is computed using the following equation: Finally, the pedestrian phase ends with the solid Don’ t Cross

Pedestrian start-up time and, consequently, an appropriate walk interval.Īt signalized intersections, the pedestrian phase, during which the right-of-way is given to pedestrians, consists of two intervals: 1) Walk interval typically begins with the adjacent vehicular through-movement green interval and is used to allow pedestrians to move from the curb into the crosswalk 2) Pedestrian Clearance, also referred to as flashing don’t walk (FDW) or change interval: follows the walk interval and informs pedestrians should either complete their crossing if already in the intersection or refrain from entering the intersection until the next pedestrian walk interval is displayed. In addition to examining pedestrian demand, this paper looksĪt the impact of storage areas and pedestrian push-button location on How many pedestrians are considered “high volume” and require 10 to 15 seconds, Pedestrians are considered “typical volume” and require 7 to 10 seconds, and Volume” and can be accommodated by the 4 second minimum time, how many Walk-interval guidelines as to how many pedestrians are considered “negligible Specifically, this paper seeks to add values to the Traffic Operations Handbook Quantitative model for designers to select the appropriate walk interval. Signalized intersections with varying pedestrian demand, pedestrian storageĪreas, and pedestrian push-button locations. Reports on a study that collected 1,500 pedestrian movement data from 12

Provide some quantitative guidance for walk interval selection, this paper Interval should be and provides values ranging from 4 to 15 secondsīased on qualitative pedestrian demand ranging from Negligible to High. Unfortunately, the literature is quite vague on how long the walk Them to cross entirely to the other side of The walk interval is intended to allow pedestrians toĮxit the curb ramp and enter the crosswalk. Walk interval and a change/clearance interval, during which pedestrians are At a typical signalized intersection, the pedestrian phase consists of a
