Advanced Traveler Information Systems (ATIS) provide real-time traffic and navigation information to drivers. It uses sensors and cameras to monitor traffic conditions and congestion. This data is then transmitted to drivers via signs, radio, GPS, and other displays to inform them of delays, accidents, construction, and alternate routes. Implementing ATIS requires high initial costs but can help reduce traffic, provide safety warnings, and improve road conditions once established.

49. SUMMARY
• ATIS is very useful to overcome the traffic congestion problem
• Automatic working will save National Income
• Initial setting cost of ATIS is very high
• Traffic problem in India can easy to solve by this
• Lac of land consumption is the major problem
• I think Installing ATIS at Trivandrum and Vyttila Ernakulam
help to solve traffic problem
