ABSTRACT Transportation agencies are facing problems of inadequate capacities to meet growing traffic demand. Street widening, signal operations optimization, innovative designs and multimodal transportation modes are traffic management strategies that can improve traffic operations along congested corridors. The goal of this paper is to assess future 2040 traffic and transit conditions along sections of Redwood Road in Salt Lake County, Utah, and develop and test potential operational improvements through VISSIM traffic simulation. Potential improvements, such as street widening, signal optimization, transit exclusive lanes with Transit Signal Priority (TSP) and adding a Continuous Flow Intersection (CFI) are analyzed. The improvements tested showed potential for reducing vehicular travel times between 6% to 20%, and delays 25% to 35%. Transit travel times reduced up to 40%, with delay reductions up to 60%. A combination of different strategies has the potential to improve traffic and transit operations along the busiest sections of Redwood Road.

容量和过境改善对交通和过境运营的影响

摘要 交通运输机构面临着能力不足的问题，无法满足日益增长的交通需求。街道拓宽、信号运行优化、创新设计和多式联运模式是交通管理策略，可以改善拥挤走廊的交通运行。本文的目标是评估 2040 年犹他州盐湖县雷德伍德路沿线的未来交通和交通状况，并通过 VISSIM 交通模拟开发和测试潜在的运营改进。分析了潜在的改进，例如街道加宽、信号优化、具有公交信号优先级 (TSP) 的公交专用车道以及添加连续流交叉路口 (CFI)。测试的改进表明，有可能将车辆行驶时间减少 6% 到 20%，延迟减少 25% 到 35%。过境旅行时间减少多达 40%，延误减少多达 60%。不同策略的组合有可能改善红木路最繁忙路段的交通和公交运营。
