| 摘 要： | 提出了一种基于交通流模型的计算道路权重方法。实施定点道路截面雷达试验并采集交通流信息，标定生成交通流速度-密度模型。通过此模型，利用出租车行驶数据库中各条道路车速数据计算各道路车流密度，根据各道路长度和密度推算道路权重。

| Abstract: | A new method based on traffic volume model is proposed to calculate road weight. First, the paper implements the spot-fixed radar detection speed experiment to acquire the data of vehicles driving. Then, the speed-density models of trunk roads and sideways are calibrated based on the data. Road lengths can be obtained through road information database. Likewise, the average speeds can also be obtained through road match-based taxi database. Furthermore, with the help of road length and density, the roads weight can be calculated. |
