Evaluation Index of Traffic Functions of Specific Emergency Transportation Roads and Its Application to Seismic Retrofit Promotion Plan

We proposed new indexes (section arrival rate and comprehensive arrival rate) to evaluate the traffic functions of specific emergency transportation roads and developed a simulation system to extract reachable road sections by describing the spatial movement of emergency vehicles. Furthermore, we developed application software that enables us to easily evaluate the impact of seismic retrofitting of specific roadside buildings on traffic functions in order to support the planning process by municipality officials. By analyzing the execution log of the application usage by the officials, we discussed their strategies for promoting the seismic retrofitting of specific roadside buildings.
