2013 - EU - Potential for NRAs to provide energy reducing road infrastructure
MIRAVEC Report D3.1. This report details the spreadsheet tool developed to aid NRAs in the assessment of fuel consumption. The tool has brought together a number of different models and studies of fuel consumption and incorporates: The effect of road roughness on fuel consumption (measured using IRI) The effect of macro texture depth on fuel consumption (measured using MPD) The effect of road geometry on fuel consumption (measured using the degree of curvature and rise and fall/gradient) The effect of vehicle speed on fuel consumption. The tool estimates the average vehicle speed from the road geometry, the level of traffic and the split of heavy to light vehicles. In addition, a simple method for estimating the effect of idle time due to traffic congestion has been developed and implemented.
