| Abstract | Fuel cost is a major portion in vehicle operating cost for motor vehicles. This research study analyzed the data collected through a random questionnaire survey of 109 vehicles within the Bangkok Metropolis based on their daily car usage. Fuel consumption varies with traffic states, non-congested and congested traffic conditions. In this research, the before and after studies are conducted to investigate the effect of traffic on fuel economy in Bangkok by considering school on session and term-break session, respectively. More than 27% saving in fuel consumption was noticed, when vehicles travel at speed range of 35-40 kph. compared with vehicles travel at speed less than 20 kph. Vehicles with engine capacity above 2000 cc were found to consume 30% more fuel than those vehicles with engine capacity in 1200-1500 cc range. Furthermore, not only fuel economy was found to be significantly different between the two study sessions but also travel speeds on peak periods of both study sessions were found to be significant different at 5% significant level. This research also formulated the vehicle fuel economy model, by utilizing regression technique, based on principal parameters and operating characteristics of vehicle. This model expressed the relationship between fuel consumption and travel speed of vehicle as the form of power equation. It showed that the increase in fuel consumption rate inversely related to the vehicle speed corresponding to traffic speed. |
