- Abstract summary: We design a route planning algorithm based on deep reinforcement learning for pedestrians.
We propose a dynamically adjustable route planning (DARP) algorithm, where the agent learns strategies through a dueling deep Q network to avoid congested roads.
Simulation results show that the DARP algorithm saves 52% of the time under congestion condition when compared with traditional shortest path planning algorithms.

- Abstract: Route planning is important in transportation. Existing works focus on
finding the shortest path solution or using metrics such as safety and energy
consumption to determine the planning. It is noted that most of these studies
rely on prior knowledge of road network, which may be not available in certain
situations. In this paper, we design a route planning algorithm based on deep
reinforcement learning (DRL) for pedestrians. We use travel time consumption as
the metric, and plan the route by predicting pedestrian flow in the road
network. We put an agent, which is an intelligent robot, on a virtual map.
Different from previous studies, our approach assumes that the agent does not
need any prior information about road network, but simply relies on the
interaction with the environment. We propose a dynamically adjustable route
planning (DARP) algorithm, where the agent learns strategies through a dueling
deep Q network to avoid congested roads. Simulation results show that the DARP
algorithm saves 52% of the time under congestion condition when compared with
traditional shortest path planning algorithms.

In the offline scenario, an environment map is created once, and fixed path planning is made on this map to reach the target.
In the online scenario, the robot moves dynamically to a given target without using a map by using the perceived data coming from the sensors.
