Automated truck lanes (ATL) is a future technology for alleviating high proportion of truck usage. This paper proposes a hybrid microscopic-mesoscopic traffic simulator that can be used to precisely estimate the changes in traffic flows that would result from introduction of ATL on large-scale road networks. An integration framework is designed to ensure consistency of route choice and synchronization between mesoscopic and microscopic simulators. Microscopic car-following and lane-changing models are extended to reflect detailed interactions between cars and trucks. Three cases are simulated to evaluate the impact of ATL on traffic flows, proportion of trucks, travel time, and performance in total travel time saving. Finally, an analysis of safety and the effect of road incidents on travel time are also conducted using the hybrid simulator. Simulation results indicate that ATL can change traffic volumes not only on the expressway itself (New Tomei-Meishin Expressway) but also on the other expressways in the network, leading to shorter travel times and improved safety. For a more precise evaluation, the ATL system should be analyzed as part of a large-scale road network.
摘要自动货车车道（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.
