Evaluation of R1-6 Gateway Treatment Alternatives for Pedestrian Crossings: Follow Up Report
Monthly follow-up data confirmed that permanent in roadway installations of the R1-6 gateway treatment led to an increase in the percentage of drivers yielding to pedestrians at midblock and multilane urban and suburban locations from 15% to 70% and that these increases endured without any decrement over the spring, summer and fall of 2016. Speed data collected at each site showed 4 to 5 mph reduction in mean when motorists traversed the crosswalk when pedestrians were absent. These speed changes persisted over time. An additional study showed that placing the signs between 5, 10, 20, 30, and 50 ft in advance of the crosswalk were equally effective and they enticed drivers to yield further ahead of the crosswalk. Data on sign survival showed that signs mounted on a curb type mount with a flexible rubber attachment all survived while only 58% of the flush mounted signs with a pivoting base survived. Data showed that none of the signs mounted on top of the edge of a curb on a refuge island or median island, curb extension, or the curb on the edge of the roadway under FHWA permission to experiment were destroyed or damaged.
