Cleaner vehicle buses in Winchester

In order to evaluate the effects of these measures, data was collected from the bus operator Stagecoach regarding their fleet of 59 vehicles in Winchester. This included their emission standard, reliability, average age and smoke test results. Emission modelling was carried out using a vehicle activity model on a key city centre street to assess emissions savings as a result of the implemented measures. In addition, two bus questionnaire surveys were carried out to assess passenger's views of the two diesel/electric hybrid buses used during the trials. Conclusions and recommendations have been made with regard to the environmental impact of the cleaner Winchester bus fleet and the contribution it has made to reducing emissions from motor vehicles in the Winchester central area.
