J2−1: Indiana Expert System for Advanced Traveler Information
The Indiana Expert System is an advanced traveler information system (ATIS) that has been used in work zones to provide traveler information. The expert system enables the traffic management center (TMC) staff to program messages to travelers from the TMC, remote locations, or from their vehicles at the site of an incident. The Indiana Expert System can send these messages to highway advisory radio (HAR), variable message signs (VMS), pagers, etc. simultaneously.
REASON(S) FOR ADOPTING:
The Indiana Expert System was adopted to reduce the time required to deliver real−time messages to the public, minimize the number of people involved in the process, and inform travelers of traffic conditions so they can make informed decisions.
The biggest benefit realized is improved traveler information, including for work zones.
MOST APPLICABLE LOCATION(S)/PROJECT(S):
The Indiana Expert System is most applicable to urban and rural freeways.
