Fuel costs cut by routing device

A vehicle routing model that can direct a driver to the most fuel efficient route has been developed in an attempt to cut CO2 emissions and fuel costs.

The computer model, called VREAM, calculates the amount of CO2 emitted from road journeys, as well as time and distance. It works by selecting roads on which a vehicle can maintain the optimum speeds that minimise fuel consumption.

The development comes as concerns about the rising cost of petrol and our carbon footprints are growing rapidly.

The VREAM model has been developed by Dr Andrew Palmer from the Centre for Logistics and Supply Chain Management at Cranfield School of Management.

He said: "The aim has not been to produce new mathematical theories, but to produce a pioneering basis for routing which will provide new information and knowledge about how CO2 emissions vary for different minimisation and congestion criteria."

The results of research show that fuel consumption, and therefore CO2 emissions, can be reduced by over 5% if the most fuel efficient routes are used.
