Abstract

Several cities throughout the world have implemented bus-only lanes to alleviate transit delays caused by traffic congestion. This paper describes design features of effective bus lanes and discusses institutional barriers to bus-only lanes, such as objections to photo enforcement and reductions in mixed-flow vehicle capacity. London is cited as an example of a city with a successful bus-only lane system. Although San Francisco has also implemented bus-only lanes, the authors suggest that the system could be improved by standardizing operating hours, signage and markings; improving enforcement; improving traffic operations; and civil and streetscape improvements.
