Transport add-on environmental modelling system (TRAEMS) is a GIS-based environmental modelling system designed to evaluate the environmental consequences of road traffic in urban areas. Its development has been underpinned by the premises that the evaluation of road traffic impacts is best undertaken during the early planning stages of road networks, and that this can utilise much of the data generated by the transport planners themselves as they apply their travel demand models as to planning of road networks. The system integrates information about traffic-usually from travel-forecasting models-with information about land use, to provide the input data to a range of commonly used models that estimate pollution from a road traffic system, and the energy consumption of that system. TRAEMS facilitates this integration and allows land use, transport and environmental planners to have rapid feedback on the environmental effects of road transport network scenarios that are being developed and tested. Its purpose is to aid in the selection of environmentally-preferred road networks and to highlight where management of pollution levels on future road networks will be required. TRAEMS has a modular structure. This paper describes the main features of the air pollution and fuel consumption modules of the system and illustrates the system's utility through case studies at both metropolitan-wide- and local-area scales.
交通附加环境建模系统（TRAEMS）是一个基于地理信息系统（GIS）的环境建模系统，旨在评估城市地区道路交通的环境影响。其开发基于以下前提：道路交通影响评估最好在道路网络的早期规划阶段进行，并且这可以利用交通规划者在应用出行需求模型进行道路网络规划时自己生成的许多数据。该系统将通常来自出行预测模型的交通信息与土地利用信息整合在一起，为一系列常用模型提供输入数据，这些模型用于估算道路交通系统的污染以及该系统的能源消耗。TRAEMS促进了这种整合，并使土地利用、交通和环境规划者能够对正在开发和测试的道路运输网络方案的环境影响迅速得到反馈。其目的是帮助选择环境优先的道路网络，并突出未来道路网络中需要进行污染水平管理的地方。TRAEMS具有模块化结构。本文描述了该系统空气污染和燃料消耗模块的主要特征，并通过大都市范围和局部地区尺度的案例研究来说明该系统的实用性。
