Abstract

A system and method for managing road transportation of sensitive materials using structured representations of perceived risk. The system includes a memory storing road-segment risk-perception information comprising risk labels, exposure durations, and user-defined risk tolerances. A routing interface receives a route-related request, and a data processing apparatus generates routing instructions based on comparisons of exposure durations, avoidance durations, or risk acceptability thresholds. Risk-feature maps are generated from geographic data using spatial data processing techniques, and risk labels are assigned to road segments based on intersections with risk features. The system enables user input via a graphical interface to adjust tolerances or avoidance values for distinct risk types, with visual feedback provided on aggregate temporal avoidance. The approach permits integration of subject-matter expert perception data into routing decisions by expressing risk avoidance as a temporal cost, allowing risk-informed route evaluation using conventional time-based routing algorithms.

Dependent claims

A system for managing road transportation of sensitive materials through a geographic, the system comprising:

a memory configured to store road-segment risk-perception information that includes, for each of a plurality of road segments of the geographic region, one or more risk labels identifying respective types of risk to which the sensitive materials would be exposed while being transported over the road segment,
a routing interface configured to receive, from a user, a request for information related to a route along which a vehicle is to transport the sensitive materials, wherein the route includes a plurality of the road segments of the geographic region, and wherein at least some of the road segments are individually avoidable by exiting the route at one end of the road segment and rejoining the route at the other end after traveling along one or more off-route roads;
and
a data processing apparatus communicatively coupled with the memory and the routing interface, the data processing apparatus configured to:
access the route-related request from the routing interface,
retrieve, from the memory, a portion of the road-segment risk-perception information associated with the plurality of the road segments of the route,
generate, based on the retrieved portion, an instruction for operating the vehicle to transport the sensitive materials along the route, and
output, to the routing interface, the generated instruction to be used by the vehicle operator.

A method for managing road transportation of sensitive materials through a geographic region, the method comprising:

storing, in a memory, road-segment risk-perception information including, for each of a plurality of road segments of the geographic region, one or more risk labels identifying respective types of risk to which the sensitive materials would be exposed while being transported over the road segment;
receiving, via a routing interface, from a user, a request for information related to a route along which a vehicle is to transport the sensitive materials, the route comprising a plurality of the road segments of the geographic region, wherein at least some of the road segments are individually avoidable by exiting the route at one end of the road segment and rejoining the route at the other end after traveling along one or more off-route roads;
accessing, using a data processing apparatus, the route-related request;
retrieving, from the memory, a portion of the road-segment risk-perception information associated with the route;
generating, based on the retrieved portion, an instruction for operating the vehicle to transport the sensitive materials along the route;
and
outputting the instruction to the routing interface for use by the vehicle operator.
