The Quantm system has helped planners find big cost savings on both large and small road projects. The rapid generation of alternatives and the ability to determine environmental impacts are also valuable benefits of the Quantm system for smaller projects.
Statewide or Regional Road Planning
The Quantm technology is used from preliminary scoping at a regional level to the development of full statewide transportation planning. The 1000 mile Trans-Texas Corridor Study greatly benefited from the Quantm system during the corridor alternatives evaluation process.
Quantm enabled the planners and engineers to consider an extensive range of options. They were able to review various “what if” scenarios and test a series of geometric parameters quickly, to consider numerous planning alternatives, and avoid, minimize or mitigate the impacts on sensitive environmental resources.
The Idaho Transportation Department and their local engineering consultant applied the Quantm system to screen alternatives and selected two highway
corridors for further National Environmental Policy Act (NEPA) evaluation. In doing
so, they developed a process to screen alternatives that addresses the challenges for determining new highway corridor alternatives. This was achieved by the ability of the Quantm system to ensure comparisons on location, impact on environment, cost and compliance
with engineering criteria and to generate new alternatives rapidly.
The Okarahia Realignment project was a 2km (1.25 mile) section of State Highway 1 in New Zealand. The Quantm system
was used to improve both the horizontal and vertical alignments of the road.
In addition to meeting all defined environmental situations and avoiding constraints, the Quantm-generated alignment cut construction cost by 13%.
