摘　　要：由于用地规划、资金缺口等限制,公路改造方案往往需要通过多个方案比选才能得到,以往的方案比选和评价方法往往都是一些定性的方法,受决策者主观因素影响较大。为此提出了一种基于VISSIM仿真模拟的道路改造方案的定量化评价方法,该方法利用VISSIM仿真软件,对各种改造方案进行模拟和预测,选择合适的评价指标并根据得到的各项评价指标进行综合分析以达到比选方案的目的。以南京市绕城公路改造工程为例,结合其实际的情况应用该方法对提出的多种改善措施和优化方案进行评价比较,结果表明:车型和车道管理方案能够有效地改善交通流运营情况,提高安全水平;运用VISSIM仿真模型能得到较好地量化评价指标,对方案比选具有较大的现实意义。Due to some limits such as land using plan or funding gap limit, road reconstruction scheme often needs to be obtained through scheme comparison. But most of the previous scheme comparison and evaluation methods are qualitative methods, and are easily influenced by subjective factors. A quantitative evaluation method of road reconstruction schemes based on VISSIM simulation was put forward. The method uses VISSIM software to simulate all sorts of reconstruction scheme and select the appropriate evaluation indexes to evaluate the schemes. Taken Nanjing belt highway reconstruction project for example, this method was applied in combination with the real situation to compare and evaluate all the proposed improvement measures and optimization schemes. The result shows that （1） vehicle management and lane management can effectively improve traffic operation condition and improve road safety level; （2） the VISSIM simulation model can obtain better quantitative evaluation indexes and has large practical meanings to scheme comparison.
