Improving vehicle speed estimates using street network centrality

Abstract: This paper describes a novel approach to improve prediction models which estimate vehicle speeds and their diurnal variation for road network links in urban street networks using only static map attributes. The presented approach takes into account previously neglected spatial information by integrating network centrality measures for closeness (indicating how central a link is) and betweenness (indicating how important a road link is) into the prediction model. The model is calibrated with a real-world datase… Show more

“…Tseng et al [21] extend these methods to suburban highways. Graser et al [8] and [9] suggest the usage of different road network centrality measures as predictors for link traveling speed. However, these authors acknowledge that some of the measures depend on the boundaries of the chosen map which introduces some arbitrariness to the approach.…”
