Abstract
Recently, several studies have tried to reveal the level of service of traffic flow using data collected with probe cars. In particular, it was reported that the variation of spot speed along the flow direction could be larger than previously believed on two-way two-lane (TWTL) expressways. Although the variation may be due to driver behaviors such as longitudinal alignment and merging at the end of auxiliary lanes, guidelines to effectively improve locally reduced speeds have not been published. Toward this end, in this study a model predicting the speed profile in TWTL sections is proposed. This model is mainly composed of three terms expressing “gradual attenuation” along the flow direction, “merging conflict” causing slow-down after the end of an auxiliary passing lane, and “local speed reduction” at sag sections. The model is calibrated with probe car data collected on representative TWTL expressways in Japan. With respect to the root mean square error, the accuracy of estimation was acceptable. Finally, a future direction for further improvement and way to implement the model are discussed.
