This invention discloses a disaster prevention living circle optimization method based on evacuation-search virtual emergency route finding features, comprising: S1: extracting the spatiotemporal boundary of the disaster prevention living circle; S2: establishing emergency action units of the disaster prevention living circle; S3: establishing a virtual emergency route finding spatial model of the emergency action units; S4: establishing evacuation-search virtual emergency route finding interactive functions; S5: conducting evacuation-search virtual emergency route finding experiments; S6: analyzing the effectiveness index and route finding feature correlation index of the virtual emergency route finding experiments to obtain evacuation-search multi-role emergency route finding features; S7: proposing a disaster prevention living circle optimization strategy.

A technique for interacting with map-related information integrates the use of a machine-trained language model. Upon submission of a query, the technique uses the machine-trained language model to assess at least one intent associated with the query. The technique then invokes an intent-specific processing flow to provide an output result. Each processing flow invokes the use of at least one processing engine to perform an engine-specific task, such as geocoding, route finding, or image retrieval. A processing flow can also call on the machine-trained language model one or more additional times. In some cases, the technique includes a feedback mechanism for soliciting additional information from a user.

An information processing unit (2) according to the present disclosure comprises a route finding unit (23) that performs an evaluation process of assessing whether at least one of a first stop or a second stop will occur on each of route candidates, based on signal information representing a light color change time of a traffic signal system and traffic congestion information representing a situation of the occurrence of traffic congestion, and determines a route to be traveled by a vehicle (1) from the route candidates using an evaluation result obtained by the evaluation process, wherein the first stop is a stop of the vehicle (1) due to a light color of the traffic signal system, and wherein the second stop is a stop of the vehicle (1) due to a traffic congestion.and the route candidates are candidates for a route from a boarding point to a destination of a user-passenger of the vehicle (1).

A computer-implemented method executed by data processing hardware of a robot causes the data processing hardware to perform operations including obtaining a topological map including waypoints and edges. Each edge connects adjacent waypoints. The waypoints and edges represent a navigation route for the robot to follow. Operations include determining, that an edge that connects first and second waypoints is blocked by an obstacle. Operations include generating, using image data and the topological map, one or more alternate waypoints offset from one of the waypoints. For each alternate waypoint, operations include generating an alternate edge connecting the alternate waypoint to a waypoint. Operations include adjusting the navigation route to include at least one alternate waypoint and alternate edge that bypass the obstacle. Operations include navigating the robot from the first waypoint to an alternate waypoint along the alternate edge connecting the alternate waypoint to the first waypoint.
