Study on Fuel Consumption Estimation Considering the Impacts of Hybrid Vehicle Promotion Based on Time Sharing of Driving Regimes from Probe Data in Bangkok

Abstract

The main objective of this study is to estimate the impacts of introducing hybrid vehicles on fuel consumption reduction in central area of Bangkok by using a model for fuel consumption estimation of vehicles based on time sharing by four driving regimes from probe data. First, time sharing by driving regimes obtained by probe data was analyzed and its reliability was tested with observed data. Second, relationship between fuel consumption and time sharing by four driving regimes with hybrid vehicles (HVs) was determined based upon data from field test. Assuming all probe vehicles will be replaced with HV, reduction of fuel consumption was estimated by applying this relationship. Finally, influence of time sharing and average speed on fuel consumption were discussed. As a result, it was found that time sharing based on probe data was reliable. Fuel consumption reduction was significant in cruising regime, and average speed affected fuel consumption.
