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).
