providing a decision-making method for evaluation of exclusive brt lanes implementation using benefit-cost analysis –case study: tehran brt line 4

recently, the rapid growth of urbanization, in conjunction with a lack of proper transportation infrastructures, has raised traffic congestion in a great number of developing cities. the growing concern about traffic congestion persuades governments to promote public transit services which mostly need a substantial amount of money to implement.

budget limitations entice decision-makers to choose bus rapid transit (brt) systems as a less expensive solution. the implementation of brt lines always comes with advantages and disadvantages. furthermore decision-makers need a tool to evaluate the effects of converting a mixed-flow lane to a brt lane. the main aim of this paper is to provide a decisionmaking criterion for the problem of lane conversion for brt. to do so, benefit-cost analysis (bca) is applied, and finally, we assess tehran brt line 4, as a case study, in order to evaluate the impact of dedication of one lane to brt on chamran highway.
