OBSERVATIONS OF FUEL SAVINGS DUE TO THE INTRODUCTION OF 'RIGHT-TURN-ON-RED'

A before-and-after comparison of data collected by driving on a fixed circuit in downtown Detroit showed a 6 per cent decrease in fuel consumption and a 12 per cent decrease in travel time after the introduction of the generally permissive right-turn-on-red policy. The observed fuel consumption was in satisfactory agreement with results calculated from the observed trip time using a previously developed linear model, although there were some discrepancies. Savings of both fuel and time were greater in off-peak traffic than in the afternoon rush hour. Of the total time saved, most (63 per cent) was saved in blocks involving a right turn on red, but 37 per cent occurred on other blocks. Similarly, most of the time savings consisted of reduced stopped delay, but there was also a 35 per cent reduction in running time. /Author/TRRL/
