Research on the Impact of Divers’ heart rate on Longitudinal Slope of FreewayTunnel

摘要

This paper researched the longitudinal slope of a tunnel from the driver’srnpsychological view, and analyzed the heart rate changes in different drivers.rnAccording to the measured data, we established the quantitative model between therndriver’s physiological and psychological response by an increased heart rate, and thernlongitudinal slope of the tunnel and running speed with a regression analysis. Thisrnmodel proved capable of describing the response of drivers driving through therncontrast between field data and model calculated data. Finally, we calculated a safernslope of the tunnel and security pace value according to the model.
