NextBus uses GPS technology and advanced computer modeling to track buses and streetcars on their routes. To estimate a bus’s arrival, NextBus takes into account the actual position of the transit vehicle, the intended stops, and the typical traffic patterns. These estimates are updated constantly as the vehicle is tracked. Information from a GPS receiver aboard each bus is relayed to the server. The NextBus system uses it patented predicative software, Passenger Information Everywhere, in conjunction with Automatic Vehicle Location (AVL) devices to predict the actual arrival time.

Transit riders can access arrival information via a variety of wireless devices, 60 to 70 different models, including

• Wireless phones with text messaging
• WAP enabled devices
• HDML-supported devices
• Web-enabled Palms with web clipping
• Other Internet devices supporting Avant-Go and mini-HTML

When traffic, weather, vehicle breakdowns or other conditions arise, commuters receive advanced notification of the delay. Cities that have installed NextBus Information Systems will soon be able to offer their transit riders the benefits of the Passenger Information Everywhere software application.
