OPERATIONAL EFFECTS OF RIGHT TURN ON RED IN NEW JERSEY. FINAL REPORT

This study was conducted to measure the effects Right Turn on Red (RTOR) had on delay and accidents at signalized intersections in New Jersey. Since its implementation in January 1977, stopped vehicles saved an average of 3.0 seconds/vehicle and approach vehicles saved an average of 1.4 seconds/vehicle. Five percent of the pedestrians were delayed in some manner by RTOR vehicles. The accidents were studied by comparing the change in accidents at test intersections which allowed RTOR at all approaches with the change in accidents at control intersections which prohibited RTOR. RTOR caused a significant increase in accidents at intersections which involved a state highway. During the period 1978-1981, approximately 3,000 accidents/year were caused by the allowance of RTOR. No change in accidents was found at intersections involving only county and/or local roads over the same time period.
