自动货车车道(ATL)是一项缓解城际高速公路货车比例偏高问题的下一代物流技术.本文提出了一种微观-中观混合交通仿真器,用于精确评估在大规模公路网上引入自动货车车道所引起的交通流变化,并设计集成框架以确保路径选择与微观-中观仿真器校核的一致性,使用扩展后的微观车辆跟驰模型和车道变换模型反映轿车与货车之间的相互作用.通过3个仿真案例评价自动货车车道对交通流、货车比例、旅行时间及总旅行时间节省的影响.最后,使用混合仿真器分析道路的安全性和交通事故对旅行时间的影响.仿真结果表明:引入自动货车车道改变了New Tomei-Meishin高速公路及该路网中其它高速公路的交通量,缩短了旅行时间,提高了安全性.应在大范围公路网络中分析自动货车车道系统,从而获得更精确的评价.
Automatic freight lane (ATL) is a next-generation logistics technology that alleviates the problem of high proportion of inter-city expressway trucks.This paper presents a micro-mesoscopic hybrid traffic simulator for accurate assessment of the large-scale road network introduced automatic Traffic flow changes caused by the truck lane and design an integrated framework to ensure that the path selection and micro-meso-simulator check consistency, the use of extended micro-car-following model and the lane change model reflects the car and truck between Interaction.According to three simulation cases, the effects of automatic truck lane on traffic flow, truck ratio, travel time and total travel time saving are evaluated.Finally, the hybrid simulator is used to analyze the road safety and traffic impact on travel time. The results show that the introduction of automatic truck lanes changes the traffic volume of New Tomei-Meishin Expressway and other expressways in the road network, shortens the travel time and increases the safety.Auto-truck lane system should be analyzed in a wide range of highway networks, In order to get more accurate evaluation.
