Abstract: Analysis of the performance of a 1-mile (1.7-km) contraflow bus lane in downtown Tel Aviv, Israel, showed that, compared to with-flow lanes, the contraflow lane demonstrated more reliable bus travel times and faster travel speeds during peak and off-peak hours. Improvements in reliability were identified using the coefficient of variation of travel times, the standard deviation of headways, and the pattern of travel-time change on successive bus runs during the peak period. An investigation of sources of delay showed that traffic-signal settings could be revised to provide significant travel-time reductions. Opportunities to improve contraflow service by limiting access to this lane by vehicles other than buses were also identified.
