Using Agency Surveys and Benefit-Cost Analysis to Evaluate Highway Advisory Radio as Regional Traveler Information and Communication Tool
Highway advisory radio (HAR) is an older strategy for disseminating traveler information, but it is still valuable for regional traveler information, especially in emergencies. To understand the continuing benefits of HAR, two online surveys were conducted with state department of transportation officials throughout the United States as well as emergency management officials in Florida. A detailed cost-benefit analysis was also conducted using customer surveys from Florida’s Turnpike Enterprise.
Based on the online surveys of state department of transportation and emergency management, ongoing benefits of HAR include:
- Provides more detail than other traveler information services, especially when detailed messages need to be shared with people in a large area
- Redundancy in the case of problems with phone- or internet-based traveler information systems
- Supplementing messages on dynamic message signs (DMSs)
- Accessing information does not require drivers’ take their eyes off the road
