At an intersection near Irving Elementary School in the Village of Oak Park, IL, motorists picking up and dropping off their kids often move too fast, so the Village intends to implement changes to calm traffic at this location. The plans call for a “neckdown” to give strong visual cues to motorists, slow traffic and shorten the pedestrian crossing distance. The challenge: what should the turning radius be so that buses can comfortably make the turn?
Before pouring concrete bumpouts and moving drainage/utilities, the Village decided to test the intended configuration with DEZIGNLINE’s PEDRAIL. They knew that PEDRAIL could be installed — and uninstalled — quickly and cost effectively into the concrete surface, and would give them the flexibility to easily test different curb extension geometries.
RESULTS: The neckdown reduced the pedestrian crossing distance from 31′ to 16′ and has significantly calmed traffic at this intersection. The Public Works installation crew was surprised at how easily and rapidly the system could be deployed (2.5 hours start to finish). The Planning and Engineering teams quickly discovered that the turning radius was too tight for buses, so they made a slight modification to the configuration (much easier than modifying a concrete installation).
The Village will observe and collect data from this location — and perhaps make further modifications — until the appropriate geometry has been determined. They’ll then remove and re-purpose the entire PEDRAIL system to another location in town.
