Effective route risk mitigation hinges on understanding possible hazards, threats, and regulatory restrictions. While risk mitigation to the shipment is primarily concerned with shipment security, government regulations limit the routes for specific payloads in the interest of public safety. Understanding federal, state, and local regulations for what can and cannot be transported along a specific roadway is key to compliance. To accomplish this - we previously used an in-house low resolution road network with attributes assigned by segment that indicate regulatory measures. In order to maintain regulatory attributes but also increase our node density from ~thousands to ~millions, we needed to conflate our existing network attributes onto the OSM network. Increasing our node density allows us to leverage the spatial accuracy of OSM, bi-directionality of highways and roadways, and last mile routing from a highway, to name a few. This presentation will walk through the nuanced process of mapping attributes like hazmat restrictions, HRCQ (Highway Route Controlled Quantity), radiation restrictions, tribal land designations, etc. onto the OSM network using a multi-step process implemented in PostGIS. The successful integration of regulatory attributes onto OSM yields a first-of-its-kind high resolution network for risk based routing.
Mapping and identifying people-first streets in Salt Lake City
Cities throughout the world are redesigning streets to better accommodate activity and transportation outside of a private automobile, sometimes referred to as “people-first” streets. This includes adding park space, wider sidewalks, bike/transit...
