TOWARDS A GENERAL MODEL FOR THE ENVIRONMENTAL CAPACITY OF ROADS

Environmental capacity (EC) was originally defined as the amount and character of traffic permissible in a street consistent with the maintenance of good environmental conditions. Amongst all of the road related environmental factors, noise, air pollution, and child safety were considered to be the most annoying factors. It was further indicated that the EC in most residential streets would be governed primarily by public safety, while for streets with commercial and institutional land uses it would be mostly controlled by noise or air pollution issues. A recent study on EC proposed accident risk to pedestrians as a primary determinant of EC. In general, previous studies were very common in their approach. They merely used a single-factor approach in estimating the EC, so the particular factor which produced the minimum EC became the controlling factor. The methodology proposed in the present research considers several environmental factors as simultaneous contributors to the overall quality of the environment. It introduces a scoring system of environmental quality using an Environmental Utility Function, which blends the environmental factors into a single value. This value is then used as a representative score of the road in respect of environmental quality. (a) For the covering entry of this conference, please see IRRD 895316.
