Linuxdevices.com reports that MIT researchers are testing CarTel, a GPS-enabled mobile sensor network based on Linux and Wi-Fi designed to address traffic gridlock. The story reads:
The CarTel system is used to test a growing number of automotive-related research projects at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL). In some ways, the system is similar to the recently announced Dash Express navigation system, in that it uses embedded Linux, GPS, and WiFi, and links up to a central route analysis system. Unlike Dash, however, CarTel currently lacks a display or real-time navigation and mapping features. Dash, meanwhile, offers additional location-based services and incorporates a cellular modem (850MHz triband GSM) to provide a continuous connection, switching to WiFi when available.
One way in which they are testing CarTel is deploying the technology in limos in the Boston/Cambridge to collect information on traffic conditions and even pothole locations. CarTel is being developed as a platform on which to test all sorts of car-related applications.
