Green Eco Routing, Navigation and your car computer
Some intelligent forward thinking researchers over at Hitachi, Xanavi, and Nissan have collected some data on ecological green routing that claims a 9% fuel cost savings on a test route. This technology is still in its infancy, but this is a perfect example of where a car computer can be used to accelerate development and deployment of technology. Implementing ecorouting will require Intense processing on the client or cloud for the complicated routing algorithms that factor in all the newly available data points:
· Traffic & Flow speeds
· Elevation changes and altitude
· Road quality (smooth vs. rough)
· Wind (eventually)
The cloud or development computer can also be used to coach the driver into more efficient acceleration and braking techniques which a lot of hyper milers are already using.
Eventually I imagine this type of data would help local governments prioritize road resurfacings and traffic control timings to help their citizenry become greener.
It seems like one of the key pieces to making this work would be accurate elevation Data. The paper I mentioned above used 50m resolution data from the government. One of the key data providers for elevation data seems to be intermap with 5m horizontal resolution and +/1 1m vertical. Check out their comparison chart to NASA data.
