Caliper Announces Automated Routing for Solid Waste Collection and Other Arc-Routing Applications

NEWTON, MASSACHUSETTS - Caliper® Corporation is pleased to announce the release of an automated routing application. Designed primarily to support solid waste collection services, the application will generate efficient vehicle routes for solid waste collection over a street network, and can also be used for street cleaning, newspaper/postal delivery, and other applications that require an arc-routing solution with side constraints. Developed to run as an add-in to Caliper Corporation’s TransCAD transportation planning software, this program has been successfully implemented in cities around the world, and provides a user-friendly and cost-efficient solution for collection and delivery operations.

The application reduces operating costs by attempting to create routes with minimal "deadheading." Deadheading is defined as the time when the vehicle is moving but is not in service, e.g. back tracking along a street that has already been serviced to get to another part of the service network. The application also attempts to minimize undesirable or unsafe vehicle movements, such as U-turns, and lets the user specify which streets are to be serviced by a pass in each direction and which streets can be serviced in a single pass (known as the meandering problem). Furthermore, the program can also create shifts to meet driver work requirements.

The application creates a route map and a route itinerary report. Route maps show the entire route system generated by the application with individual vehicles routes displayed using different colors. Route maps can be customized using the standard mapping functions provided with TransCAD. The route itinerary lists the sequence and direction of road segments on each route. The itinerary also includes the road name and the service mode (deadhead, right service, or both curbs) for each segment, and provides summary statistics for each route, including workload, total time, deadhead time, and the number of turns by type.
