| Summary | Weigh station operations have significant impacts on toll collection and the enforcement of vehicle weight limits on freeways. The purposes of this study are: (1) to identify weaknesses related to the current operations of the weigh stations on Sun-Yat Sen National Freeway; and (2) to examine the relationships between the operating efficiency of a weigh station and its influencing factors. First, current weight-station operating procedures are examined and their implications in law enforcement and freeway maintenance are discussed. Measures that may be taken to rectify current operational problems are then suggested. Subsequently, the vehicle-processing characteristics of weigh stations are analyzed on the basis of field observation and computer simulation. Field data reveal that a weigh station can process about 288 vehicles per hour. The Toll Plaza Simulation (TPS) Model is calibrated and tested to ensure that its estimated vehicle delays at weight stations are realistic. This model is then used to analyze the interacting operations of toll plazas and weigh stations. The simulation results are used to assess the geometric design requirements of weigh stations and the weight flow of current heavy trucks that can be efficiently processed through a weigh station during peak hours. |
