Advanced Traveler Information Systems (ATIS)
General Description:
Advanced Traveler Information Systems are aimed at providing users of the transportation system with more information with which to make decisions about route choices, estimate travel times, and avoid congestion. Most ATIS technologies are also aimed at the motor vehicle operator.
This broad category of applied technology includes the following:
- In-vehicle navigation systems (i.e. on-board computer maps) which can tell the drivers where they are and how to get to a destination
- Variable message signs that provide information about congestion from traffic, and tell drivers which lanes to use or avoid, or provide alternate route information in case of road closures
- Terminals that could provide a color-coded network map showing congestion levels on area highways (a.k.a. congestion index).
Effects of Solution:
¨ Increase Passenger Throughput
¨ Increase Roadway Capacity
þ Manage System Efficiency (Improves safety and information to motorists)
¨ Reduce Local Demand
Examples of Implementation:
See the related fact sheets for specific examples of implementation.
