This report describes an experimental study of vehicle speed and fuel consumption undertaken in the eastern Caribbean island of St Lucia. The study was designed to extend the range of the empirical relationships derived in an earlier study in Kenya which relate vehicle speed and fuel consumption to the geometric characteristics and surface condition of the road. The results of this study are compared with the relationships derived in the Kenya study and recommendations are made on the use of the two sets of relationships. a methodology has been evolved to provide vehicle speed estimating relationships which are applicable to physical and environmental conditions lying between the two sets of conditions encountered in Kenya and St Lucia.
