Relationship of Linear Combination of Tunnel and Heart Rate Increase Rate

In order to ensure mountain highway tunnel traffic safety and improve the linear combination of the tunnel design, the authors set up a model about heart rate increase rate and the linear combination of the tunnel design, using dynamic physiological detector records and physiological data in a real car test. Using the theory and method of mathematical statistics and mathematical modeling, they conduct an analysis of the relationship between heart rate increase rate and bend radius, slope and length of the tunnel and set up some regression models by SPSS. The authors analyzed and compared the effectiveness of each model. The analysis shows that it is very significant to draw a linear correlation between heart rate increase rate and the combination of bend radius, slope and length of the downhill tunnel, while the uphill tunnel section was not significant. According to the regression model, the authors discuss the discipline about the changes of heart rate increase rate with tunnel design (slope, bend radius, and length) combination, and the relationship between length and bend radius in critical conditions.
