Abstract:
Taking a single linear corridor of transit as the research object, the users’ and operators’ cost analysis models are established based on the demand data that is described as a matrix of flows between every stop of bus rapid transit(BRT). A frequency optimization model is established by setting minimum cost to be the objective function. In the modeling process, the influence of time value on the optimization results is taken into account.Taking line 1 of Changzhou BRT as an example, this paper examines the effect of this method on the optimal values of frequency. The results indicate that the amount of cost goes down first and then goes up along with the increase of frequency, and the optimal frequency is 15 veh/h. Therefore, it is suggested that the bus time headway should be 3 to 5 min on peak hours and 6 to 8 min on off-peak hours. The sensitivity of users’ cost and operators’ cost to the frequency is analyzed. It is shown that bus enterprises can reduce passengers’ waiting time costs by increasing the frequency, but it does not have a good effect on reducing the in-vehicle time costs.
