【摘要】：大多数高速公路ETC车道的长度都是以停车视距计算方法为设计依据的,但这忽视了各省市ETC交易耗时的差异,且此依据与ETC系统可实现不停车自动收费的目标相矛盾。不合理的车道长度会导致部分车辆因时间不足而无法完成交易,或出现跟车干扰等现象,降低收费站服务水平。以陕西省170多万条交易数据为样本,采用随机过程与数理统计方法,对交易耗时进行数字特征分析和参数估计,并提出ETC车道划分为交易区和安全控制区,将置信度为99.9%的交易耗时估计结果和停车制动距离应用于区域长度设计中。陕西全省ETC系统建设实践证明,该方法提高了ETC车辆通过率,保障了行车安全,取得了良好效果。
[Abstract]:Most of the length of freeway ETC lane is based on the calculation of parking sight distance, but this ignores the difference of ETC transaction time between provinces and cities. And this basis and ETC system can achieve the goal of non-stop automatic charge. Unreasonable lane length will lead to some vehicles because of lack of time to complete the transaction, or the appearance of vehicle interference and other phenomena. Taking more than 1.7 million transaction data in Shaanxi Province as a sample, using stochastic process and mathematical statistics method, the transaction time consumption is analyzed and parameter estimation is carried out. The ETC lane is divided into trading area and safety control area. The estimation results of transaction time and braking distance with confidence degree of 99.9% are applied to the design of regional length. The practice of ETC system construction in Shaanxi Province proves that this method improves the passing rate of ETC vehicles. The safety of driving is guaranteed and good results are obtained.
