Alternative intersection design. A possible way of reducing air pollutant emissions from road and street traffic

Technical Report:

Abstract

The environmental aspects of intersection design is highly neglected in the planning and construction process. It is necessary to pay attention to the infrastructural design aspects when looking for ways of reducing the traffic related exhaust pollution in the ambient air. It must be possible to find an optimal intersection design for the environment. This report is dealing with the research methodology and survey methods, which could be used in order to find the solution to the problem. Speed-, acceleration- and deceleration profiles are created with the help of field measurements of driving patterns. Data is collected from video pictures taken from a helicopter or from a high mast. Conclusions regarding the differences in pollution levels are then drawn on the basis of the obtained data from before and after micro studies of the traffic flow. The report is also including a before/after case study with a traffic signal intersection changed to a roundabout. The study gave very positive performance results for the roundabout compared with the traffic signal intersection, and as an example it was deduced that if the average driving speed through the intersection in one direction could be increased from 20 km/h to 40 km/h, the HC-emission  More>>
