摘要

一个可靠的运输网络对于通过货物运输来维持和提高一个地区的经济生产力至关重要,其中很大一部分是通过卡车运输的。应查明网络中的关键问题,并实施缓解措施,以确保将链路中断造成的负面影响降至最低。利用考虑网络、货流和经济特征的关键性措施,对加拿大安大略省高度关键路段的位置和安大略省交通部计划的基础设施改善项目进行了比较。通过情景分析探讨了四个高速公路容量扩张路段,并将其实施效果与现状基本情况进行了比较。货运和客流预测到2036年进行分析。在各种方案之间进行比较,以评估每个区段在车辆和货物价值流、旅行时间、温室气体排放和每个区段的平均操作条件方面的改进对整个网络的影响。在比较的四个路段中,404高速公路的改进似乎在网络性能方面提供了最显著的好处。这种分析可以为基础设施改进的优先次序提供政策措施,以解决网络关键问题。

Evaluating the impacts of infrastructure improvements based on link criticality and network performance: A case study of the trucking industry in the province of Ontario, Canada

A reliable transportation network is essential to maintaining and growing a region's economic productivity through the movement of goods, a significant proportion of which is moved by truck. Criticalities in the network should be identified and mitigation measures implemented to ensure that minimal negative impacts arise from link disruptions. Using criticality measures that account for network, freight flow, and economic characteristics, a comparison is made among locations of highly critical segments in the province of Ontario, Canada, and infrastructure improvement projects planned by the Ministry of Transportation of Ontario. Four highway capacity expansion segments are explored through a scenario analysis, comparing the effects resulting from their implementation to a status quo base case. Freight and passenger flows are forecasted to the year 2036 for the analysis. A comparison is made among the scenarios to assess the network-wide impacts of each segment's improvements with respect to vehicle and shipment value flows, travel time, greenhouse gas emissions, and each segment's average operating conditions. Of the four segments compared, the improvements of Highway 404 appear to provide the most significant benefits with respect to network performance. Such analysis can inform policy measures for the prioritization of infrastructure improvements to address network criticalities.
