Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools.

使用新的分析工具评估高效重型车辆在城市交通网络中的全面影响。新型创新重型车辆带来了显著的经济效益，其有效载荷可达标准半挂车的两倍。此外，这些车辆有可能减少总体事故和环境退化。这些好处需要与对其他道路使用者的影响进行权衡。这项研究将通过以下方式改善此类车辆在区域中心的运营：（1）一种评估方法，用于处理网络效率提高的选项，以反映全部影响;和（2）基于基础研究的计算机建模工具，以量化这些影响，包括延误和事故率。

Assessing the full impacts of high efficiency heavy vehicles in urban traffic networks using new analytical tools. Significant economic benefits result from new innovative heavy vehicles, which are able to carry up to twice the payload of standard semi-trailers. In addition, those vehicles have the potential to reduce overall accidents and evironmental degradation. Those benefits need to be traded-off against the impacts on other road users. This research will improve the operation of such vehicles in regional centres by producing: (1) an assessment methodology to deal with options for network efficiency gains which will capture the full impacts; and (2) a computer modelling tool based on fundamental research to quantify those impacts, in terms of delays and accident rates.
