Caliper Announces Development of an Automated Snow Plow Routing Application for Hennepin County, Minnesota

NEWTON, MASSACHUSETTS – Caliper® Corporation has announced the development of an automated snow plow routing application for the Hennepin County Department of Public Works (DPW). Developed using Caliper Corporation’s TransCAD® transportation planning software, the application will generate snow plow routes for an area covering Hennepin County, Minnesota.

At the onset of a snowstorm, Hennepin County DPW dispatches separate fleets of snowplows to service county highways. Snow plows operate individually or as a part of a multiple-truck team to improve driving conditions by clearing snow from driving lanes and shoulders, and spreading sand or salt to increase traction and accelerate melting. In prior years, snowplow routes were created manually and were designed to return highways to acceptable driving conditions within a pre-defined "cycle time," i.e. the time necessary to service all highways in a route.

The automated snow plow routing application strives to increase the level of service and to decrease operating costs by reducing snow plow "deadheading." Deadheading is defined as time when the truck is moving but the plow blade is not in service, e.g. driving from the truck station to the start of a route, or driving between service areas. In addition, the application attempts to create routes that balance cycle times.

Reports generated by the application include route descriptions that list highways to be serviced in a single route, the number of trucks assigned to a route, and the originating truck station for each route. Routes are also displayed in color maps and are further described in statistical reports that describe service time and deadhead time.

TransCAD Transportation GIS Software provides an extended GIS data model that is designed to support transportation applications, including routing and logistics. TransCAD supports the creation of transportation networks and the integration of procedures for network partitioning and vehicle routing. The commercial, off-the-shelf version of TransCAD includes a series of procedures that can be accessed directly through the product interface. In addition, Caliper Corporation’s transportation consultants and software developers can create custom procedures to meet specific end-user requirements. These routing procedures, in combination with a custom user interface and a geographic database featuring state and county highways, provide a simple, yet powerful, application for planning and managing snow removal operations.

Howard Slavin, Caliper Corporation’s president says "TransCAD integrates routing and logistics procedures with a robust GIS engine to provide support for all phases of snow plow routing in a single desktop application. End users can create and maintain highway networks, prescribe input parameters, display routes, and generate presentation quality maps and reports without having to move data between numerous applications. We are confident that our work with Hennepin County will demonstrate that TransCAD provides a complete solution for snow plow operations."

Located in Newton, Massachusetts, Caliper Corporation is a leading developer of desktop Geographic Information System (GIS) software products. Caliper has developed Maptitude GIS for Windows, GIS+, and TransCAD Transportation GIS Software.
