| 摘要： | The application of a dynamic traffic assignment model (DYMOD) to the southeast Denver metro area surrounding I-25 and I-225 is described. Hourly volume counts on 20% of network links were used to estimate a morning peak-period trip matrix between 110 zones using a three-step procedure developed to estimate origins, destinations, and the origin-destination (O-D) trip matrix. Trip departure times from each zone were estimated using 5-min counts at on-ramps to I-25. Then, 5-min volumes and speeds predicted by DYMOD for I-25 through lanes and on-ramps were compared with observed data from loop detectors. Lane-blocking incidents were modeled and compared with observed traffic volumes and speeds during these incidents. The results show that DYMOD can reproduce and predict network traffic conditions (with or without accidents) as well as generate alternative routes to reduce traffic delays during incidents. |
