Safety Evaluation Model for Traffic Operation Environment of Freeway Tunnel
This study developed a safety evaluation model for traffic operation environment of freeway tunnel based on the grey entropy weight clustering. Firstly, a safety evaluation system was proposed including four aspects related road conditions, traffic operating conditions, environmental conditions and climate condition. Secondly, whitenization weight function was defined and weights of indexes were determined by entropy theory. Thirdly, the grey entropy clustering coefficient was calculated, and the safety level for traffic operation environment of freeway tunnels was evaluated. Finally, a case study of seven tunnels of XI-HAN freeway was conducted to verify the feasibility and effectiveness of the model.
