Abstract

Developing appropriate modeling and simulation tools with the capability of analyzing traffic patterns, travel demand, and traveling/driving behavior responses at the regional level is important for the evaluation of active traffic management (ATM) and real-time transportation systems management and operations (TSM&O). In this paper, an integrated travel behavior and dynamic traffic assignment modeling tool, AgBM-DTALite, has been developed and adapted for real-time and dynamic analysis of ATM and TSM&O. The ATM algorithms are tightly integrated into the system, revising the control rates on a minute-by-minute basis. This tool also successfully incorporates travel demand and behavioral sensitivity into the traffic control and operations. The model is applied in a large-scale network to evaluate several ATM strategies, including variable speed limit (VSL) and ramp metering in the Washington, DC area. Significant departure time behavioral changes are found in response to ATM and the subsequent changes in traffic conditions. The impact on traffic dynamics is also quantified using various performance metrics.

摘要

开发能够在区域层面分析交通模式、出行需求和出行/驾驶行为响应的适当建模和仿真工具，对于评估主动交通管理 (ATM) 和实时交通系统管理和运营 (TSM&O) 非常重要。 ）。在本文中，集成了出行行为和动态交通分配建模工具 AgBM-DTALite，已开发并适用于 ATM 和 TSM&O 的实时和动态分析。ATM 算法紧密集成到系统中，每分钟都在修改控制费率。该工具还成功地将旅行需求和行为敏感性纳入了交通控制和运营。该模型应用于大规模网络以评估多种 ATM 策略，包括华盛顿特区的变速限制 (VSL) 和匝道计量。为了响应 ATM 和随后的交通状况变化，发现了显着的出发时间行为变化。还使用各种性能指标量化对交通动态的影响。
