ProMiles Permit Route Guidance


ProMiles Software Development Corporation (PSDC) is committed to the safe travel of Oversize/Overweight (OS/OW) loads. PSDC feels the complex routes created by modern Permitting and Routing Systems are difficult to follow, and this difficulty leads to vehicles going off route at times with tragic results. PSDC’s OS/OW Route Following App is designed to help the truck driver follow these complicated routes.

Because of PSDC’s commitment to safety, PSDC has committed to providing this service/app to the trucking industry at no cost indefinitely. This service is available for states that use PSDC’s Permitting and Routing Systems, as well as for states that use other vendors to create their own system.

How does the app work?

When the OS/OW Permitting and Routing System identifies a route for a permit, it obtains a list of road segments that describe the route. Each of these road segments consist of two or more lat/long points. The Permitting and Routing System uses this information to draw the route line on the map. This information is called a breadcrumb trail for the route. This trail describes the roads the vehicle is traveling on to a high level of precision. This breadcrumb trail and the associated maneuver directions are utilized to create the data for the Route Following app.

When a driver selects a route to follow, the app will reach out to a ProMiles App server to obtain the information for the permit. The ProMiles App server will then connect to the State Permitting and Routing System to find the route following information. If the route information is available in the State Permitting and Routing System, it will be sent back to the ProMiles App server. See diagram:

The app will obtain the current lat/long coordinate of the device and truck, and if within the threshold of on the route, the app will enter Route Following mode. In this mode, the app will display the trip line, the vehicle, location, and the next maneuver. The app will speak the next maneuver as the driver approaches the maneuver .If the driver gets off route, the app will shut down Route Following mode and will display a message from the Permit Office instructing the driver to contact the Permit Office to return to the route.
