Abstract:
To decide an optimal route and several alternate routes under disastrous conditions, a guidance decision-making model is proposed based on the graph theory and the optimization theory. Taking freeway corridor as the research object and real-time safety reliability as the basic constraint condition, the solution method for connected routes between the initial point and the ending point is studied by using the graph theory. The optimal route decision-making model based on safety is built by the optimization theory and the optimized route is solved by the Dijkstra algorithm. On the basis of the optimized route, the conception of multiplicity and the corresponding algorithm are introduced to study the models of other alternate routes. Aimed at the freeway corridor, the traffic route guidance decision-making model under disastrous conditions is proposed to solve the route decision taking safety, travel time,and traffic demand into consideration comprehensively. The results show that all connected routes between the initial point and the ending point can be solved by the graph arithmetic and the optimized route can be solved by the Dijkstra algorithm. Furthermore, other alternative routes can be solved by the multiplicity algorithm to satisfy route requirements under disastrous conditions.
