(First Embodiment)
First, with reference to FIG. 1, an outline of the overall configuration of the road traffic management system S of the first embodiment will be described.
FIG. 1 is a block diagram showing an outline of the overall configuration of the road traffic management system S of the first embodiment. The road traffic management system S includes a power generation company 1, a consumer 2, an automobile company 3, an aggregator (power transmission and distribution company) 4, a charging service company 5, an EV user management company 8, and a road company. 9 and EV10 are provided. Of these configurations, a collection of configurations related to charging reservation, including the charging reservation management server 82 and the mobile terminal 103 (user terminal), is referred to as a charging reservation system.
