Summary

This report evaluates the efficacy, configuration, and cost-effectiveness of the "Gateway" treatment for pedestrian crossings, which utilizes R1-6 in-street signs. Conducted by Western Michigan University for the Michigan Department of Transportation (MDOT), the study addresses the need for low-cost countermeasures to improve driver yielding on multilane roads, where traditional single in-street signs have proven ineffective. The research compares the Gateway treatment against more expensive alternatives like Rectangular Rapid Flashing Beacons (RRFBs) and Pedestrian Hybrid Beacons (PHBs), aiming to determine optimal sign placement, long-term persistence, and survival rates. The study employed a series of field experiments across multiple sites in Michigan, utilizing a repeated-measures design to compare driver yielding behavior under various conditions. The Gateway configuration consists of R1-6 signs placed on the centerline, both roadway edges, and lane lines. Researchers tested several variables: the impact of sign message versus blank signs, the effect of gap narrowness between signs, and alternative placements such as mounting edge signs on the curb face rather than in the gutter pan. They also substituted robust flexible delineators for lane-line signs to assess durability. Data collection included measuring driver yielding percentages, vehicle speeds, and sign survival rates over time, including periods of permanent installation and seasonal removal for winter maintenance. Results demonstrated that the Gateway configuration was markedly more effective than using signs only on the centerline or lane lines. Narrower gaps between signs correlated with higher yielding rates. Crucially, the presence of the R1-6 message was significant; a Gateway of blank signs was significantly less effective than one with the standard yield message. Mounting edge signs on the curb face was nearly as effective as gutter pan placement but offered better protection from vehicle strikes and snowplows. Replacing lane-line signs with robust delineators resulted in only a modest reduction in efficacy while significantly improving sign survival. The treatment also induced gradual speed reductions, with drivers slowing at the dilemma zone. Effectiveness varied by application: the Gateway was highly effective at trail crossings and RRFB sites, moderately effective at roundabouts, and marginally effective at interstate entrance ramps, where it was not recommended. The study concludes that the Gateway treatment is a robust, cost-effective alternative to high-cost electronic beacons, particularly on multilane roads. It provides significant improvements in driver yielding and speed reduction without requiring pedestrian activation. The findings suggest that optimizing sign placement—such as using curb-top mounts and durable delineators—can enhance longevity and reduce maintenance costs. While preliminary data indicated sustained effects over two to three months, further long-term studies are needed to confirm persistence. The report provides MDOT with evidence-based guidelines for deploying this treatment to maximize pedestrian safety benefits within limited financial resources.

Key finding

The full R1-6 gateway configuration significantly increased driver yielding rates compared to partial sign placements or blank signs, with narrower gaps between signs correlating to higher yielding behavior.
