Abstract
A major cause for air pollution in urban areas is exhaust emissions from vehicles. Vehicular emissions are mainly caused due to high volume of traffic and changes in driving speeds. Traffic management measures can reduce the vehicular emissions by smoothing traffic flow. One way to achieve a smoother flow of traffic is to synchronise the signals. Implementation of this method can lead to lower vehicular emission levels compared to that of interrupted traffic flow. This paper presents a study on evaluation of signal interruptions on vehicular emissions through a case study. Essentially, the study methodology relies on field runs of selected vehicles in interrupted and uninterrupted modes. In the process of these runs, tailpipe emissions [carbon monoxide (CO), hydrocarbons (HC) and nitric oxide (NO)] were measured using a portable gas analyser. Three motor vehicles-a two-wheeler, an auto-rickshaw and a van were selected for test runs. Tailpipe emissions from the individual vehicles were used to evaluate the total emissions from the vehicles for each test run. Several test runs were conducted on the study corridor. Emissions were compared for the interrupted and uninterrupted flow cases, to evaluate the influence of signal interruptions on emissions. © 2006 - Kalpana Corporation.
