通过将运输限制在指定的安全路线上，可以减少危险材料泄漏的潜在风险。有几个标准可用于指定安全的卡车路线，其结果差异很大。三个不同的路线策略的危险材料的道路运输进行了讨论：最小的风险，最小的事故可能性，和最小的卡车运营成本。每个路由策略应用到多伦多的道路网络，1981年的卡车事故配置文件的基础上。对推荐的安全路线进行了分析，以确定在各种环境条件下的成本效益。从成本效益分析中得出两个重要方面：（a）最小风险路由策略以增强安全性的形式产生净经济收益，以及（B）在卡车运营成本和安全收益之间发生重大权衡。这些权衡是执行这类加强危险材料运输安全战略的根本问题。
Potential risks from hazardous materials spills can be reduced by restricting shipments to designated safe routes. Several criteria can be used for designating safe truck routes with widely varying results. Three distinctive routing strategies for the road transportation of hazardous materials are discussed: minimum risk, minimum accident likelihood, and minimum truck operating costs. Each routing strategy is applied to the Toronto road network, on the basis of 1981 truck accident profiles. Recommended safe routes are analyzed for cost-effectiveness for a wide range of environmental conditions. Two important aspects emerge from this cost-effectiveness analysis: (a) the minimum risk routing strategy produces net economic gains in the form of enhanced safety, and (b) significant trade-offs occur between truck operating costs and safety benefits. These trade-offs are of fundamental concern to the implementation of this type of safety enhancement strategy for the transportation of hazardous materials.
