Research on Long Slope Alignment Based on Influence of Drivers′ Psychology

The research on the influence of the long slope alignment on drivers′ psychology is of great benefit to the design of long slope sections and traffic safety.Using mathematical statistics and mathematical modeling,a regression model of the driver′s heart rate and long slope alignment index is established as the speed and long slope alignment index are taken as independent variables.At last the paper utilizes the model to discuss the effect of the long slope alignment index on traffic safety and drivers′ psychology,and then provides technical support for long slope sections and alignment design and transformation.
