Researchers at the Massachusetts Institute of Technology used virtual tokens, cellphones and vehicle-to-vehicle wireless LANs to build a system for allocating the limited space available on major thoroughfares. It doesnt require any physical infrastructure, such as tollbooths, so it could be implemented quickly almost anywhere, they said.
Instead of using cameras or electronic tollbooths by the roadway to detect cars passing a certain point, the MIT system, called RoadRunner, is based on GPS (Global Positioning System) information from the drivers cellphone in each car. As more cars get connected to the Internet, the system may be able to go into the car itself, according to Jason Gao, a graduate student in electrical engineering and computer science who developed the system with Professor Li-Shiuan Peh.
