8 car platoon

1. DEMO '97 in SAN DIEGO, CALIFORNIA.
August 7-10, 1997.


This platoon control demonstration was held in San Diego by the National Automated Highway System Consortium (NAHSC). PATH showed an 8 Buick LeSabre platoon in combined longitudinal and lateral control on the I-15 HOV lanes. The vehicles were driving themselves at 6.5 meters spacing and 60 mph. The scenario involved vehicle #2 splitting, doing a lane change, falling back and doing another lane change to join the platoon back as vehicle #8. PATH also showed a single Buick mini-demo at Miramar College, which Senator Boxer rode. The vehicle was fully automated, going forward and in reverse, on a tight course set up with cones.

The demonstration was such a success that, in February 1999, the PATH team received the UC Distinguished Service Award.
