## Abstract

An automated driving vehicle management apparatus according to an embodiment is a vehicle management system that manages a vehicle traveling along a traveling route, the vehicle management system including: a map information acquisition unit that acquires map information including a road on which a vehicle travels; a sensor that detects environmental information about another vehicle or a passerby, the sensor being disposed in a traveling environment including the road and an area around the road; a generation unit that generates, based on the map information and the environmental information, traveling information about a traveling speed of the vehicle on the traveling route or about whether or not the vehicle can pass through the traveling route; and a communication unit that transmits the traveling information to the vehicle.

## Claims

### Claim 1

A vehicle management system configured to manage a vehicle that travels along a traveling route, the vehicle management system comprising:
a map information acquisition unit configured to acquire map information including a road on which the vehicle travels;
a sensor configured to detect environmental information about another vehicle or a passerby, the sensor being disposed in a traveling environment including the road and an area around the road;
a generation unit configured to generate, based on the map information and the environmental information, traveling information about a traveling speed of the vehicle on the traveling route or about whether or not the vehicle can pass through the traveling route; and
a communication unit configured to transmit the traveling information to the vehicle.

### Claim 2 (depends on 1)

The vehicle management system according to claim 1, wherein
the vehicle is an automated driving vehicle,
the communication unit transmits the traveling information about the traveling route to the vehicle, and
the vehicle travels on the traveling route in accordance with the traveling information.

### Claim 3 (depends on 1)

The vehicle management system according to claim 1, wherein
the traveling route includes a plurality of nodes that are associated with coordinates of the map information and a link that connects the nodes to each other,
the node is associated with passage feasibility information indicating whether or not the node can be passed through, and
the link is associated with the traveling speed.

### Claim 4 (depends on 1)

The vehicle management system according to claim 1, wherein the generation unit predicts a behavior of the another vehicle or the passerby based on the environmental information, and generates the traveling information based on a result of the prediction.

### Claim 5 (depends on 1)

The vehicle management system according to claim 1, wherein
the sensor detects an actual speed of the vehicle, and
when the actual speed exceeds the traveling speed of the traveling information, the communication unit transmits warning information to the vehicle.

### Claim 6 (depends on 1)

The vehicle management system according to claim 1, wherein a warning is issued to a driver of the another vehicle or the passerby in accordance with the traveling information.

### Claim 7

A vehicle management method for managing a vehicle that travels along a traveling route, the vehicle management method comprising:
