Evaluating the Performance of Right-Turn-On-Red Operation at Signalized Intersections (with single and dual right-turn lanes)

The objectives of this research are to (1) evaluate methods for evaluating right-turn-on-red (RTOR) at signalized intersections (right-turn configurations including shared, single, and dual right-turn lanes); (2) develop methods and tools that consider all modes and inform planning and operational decisions; and (3) provide potential modifications to standard references in the Highway Capacity Manual (HCM), NCHRP Report 812: Traffic Signal Manual, and the Manual on Uniform Traffic Control Devices (MUTCD). The final report shall summarize the work performed on the previous tasks, along with significant conclusions and recommendations for implementation. It should include the following at a minimum: (1) Methods for estimating RTOR flow rate; (2) Methods for estimating the effect of RTOR flow rate on approach vehicular delays; (3) Evaluation of any effects to motorized and non-motorized safety that may derive from the proposed methods; (4) Recommendations on motorized and non-motorized criteria regarding the implementation of RTOR; (5) Guidance for operations on both pre-timed and actuated signal controls; (6) Case examples of the proposed method application; and (7) Suggested modifications to standard references in the HCM, MUTCD, ITE: Guidelines for Determining Traffic Signal Change and Clearance Intervals, Traffic Engineering Handbook, and NCHRP Report 812: Traffic Signal Timing Manual, written in an appropriate format for review, revision, and concurrence for future updates and included as an appendix.
