Transit agencies across Canada are experiencing increased challenges to offer reliable services to passengers along the congested urban corridors. In the case of British Columbia (BC) Transit, the cost of transit delays due to traffic congestion through the midtown corridors along Enterprise Way and Springfield Road of Kelowna is estimated approximately $300,000 annually. Around one-third of transit trips in Kelowna pass through these corridors. To address the growing reliability and cost challenges, BC Transit has identified several service improvement strategies as potential solutions. Moreover, traffic congestion is potentially influenced by the built environment characteristics of these corridors, such as presence of shopping centres, and closely spaced intersections. Further research is required to identify transit preferential treatments and built environment configurations for effectively improving service reliability at different intersections. This research develops innovative modelling methods and simulation tools for testing alternative service improvement strategies on transit reliability (i.e. travel time variation). The objectives of this study are to: 1) develop a traffic microsimulation tool for examining the impact of transit preferential treatments on travel time variation, and 2) develop statistical models for testing the influence of built environment characteristics on travel time variation. The findings of this study will assist BC Transit to identify priority investment areas for effective improvement of transit services. This improved reliability will directly benefit BC Transit through increased ridership and revenue, and reduced cost for transit delays. The increased revenue and cost savings will further facilitate investments in expanding the transit network to serve a larger segment of the population in BC. The outcome of this research will also help Canada to effectively allocate funds under the $180 billion Investing in Canada infrastructure plan on transit service improvement projects over the next 10 years. In addition to the economic benefits, Canada will have many-fold benefits from this project including reductions in traffic congestions and greenhouse gas (GHG) emissions, and improvements in population health and accessibility.

加拿大各地的过境机构正在面临越来越多的挑战，可以为拥挤的城市走廊沿岸的乘客提供可靠的服务。就不列颠哥伦比亚省（BC）的过境而言，沿着企业路和基洛纳的斯普林菲尔德路的中城走廊的交通拥堵造成的交通延迟估计约为30万美元。基洛纳（Kelowna）中约有三分之一的过境旅行通过这些走廊。为了应对不断增长的可靠性和成本挑战，卑诗省的运输已将几种服务改进策略确定为潜在解决方案。此外，交通拥堵可能受这些走廊的建筑环境特征的影响，例如购物中心的存在和紧密间隔的交叉点。需要进一步的研究来确定过境优先处理和建立环境配置，以有效地提高不同交叉点的服务可靠性。这项研究开发了创新的建模方法和仿真工具，用于测试有关过境可靠性的替代服务改进策略（即旅行时间变化）。这项研究的目标是：1）开发一种流量微仿真工具，用于检查过境优先处理对旅行时间变化的影响，以及2）开发用于测试建筑环境特征对旅行时间变化的影响的统计模型。这项研究的发现将有助于卑诗省的过境，以确定有效改善过境服务的优先投资领域。这种提高的可靠性将通过增加的乘客量和收入直接使BC过境受益，并减少过境延迟的成本。收入和成本节省的增加将进一步促进投资扩大过境网络，以服务于卑诗省的大部分人口。这项研究的结果还将有助于加拿大有效地分配了在未来10年内对加拿大基础设施计划的1800亿加元投资计划的资金。除了经济利益外，加拿大将从该项目中获得多种收益，包括减少交通拥堵和温室气体（GHG）排放，以及人口健康和可及性的改善。
