    Abstract
  • In order to increase expressway capacity and improve expressway service level, a decision-making method of optimal reconstruction time for expressway was proposed. The statistics data of traffic from expressway toll stations were analyzed, and the traffic volumes of future years were predicted by using trend extrapolation method, multinomial regression method and growth factor method. According to the service level of expressway computed with the traffic volumes, the optimal reconstruction time was confirmed when the actual traffic volume equalled to the design traffic volume. Computational result shows that the service level of Xi'an-Baoji expressway is 1.0 in 2011, which is actual optimal reconstruction time, so the decision-making method is reliable.
