本文介绍了一种综合方法的开发，用于评估大城市地区道路客运造成的环境空气质量和人口暴露。大多伦多地区基于微观模拟活动的旅行需求模型 - 家庭代理的旅行活动调度程序 - 扩展了交通排放和大气扩散的建模和绘图功能。估算了每小时基于链路的排放量和基于区域的浸泡排放量。此外，每小时的道路排放量以高空间分辨率分散，由此产生的环境空气浓度与从模型中得出的个人时间活动模式相关联，以评估个人每日暴露水平。该方法可以明确表示排放量、环境空气质量和人口暴露的时间和空间变化。 (C) 2010 Elsevier Ltd. 保留所有权利。
This paper describes the development of an integrated approach for assessing ambient air quality and population exposure as a result of road passenger transportation in large urban areas. A microsimulation activity-based travel demand model for the Greater Toronto Area - the Travel Activity Scheduler for Household Agents - is extended with capabilities for modelling and mapping of traffic emissions and atmospheric dispersion. Hourly link-based emissions and zone-based soak emissions were estimated. In addition, hourly roadway emissions were dispersed at a high spatial resolution and the resulting ambient air concentrations were linked with individual time-activity patterns derived from the model to assess person-level daily exposure. The method results in an explicit representation of the temporal and spatial variation in emissions, ambient air quality, and population exposure. (C) 2010 Elsevier Ltd. All rights reserved.
