Thailand Highway Traffic is a free travel and navigation app developed by Thaivisa Expat Group Co. Ltd. that provides access to more than 100 traffic cameras on the highways. The app offers real-time traffic updates, including the latest speed(km/h) and flow(veh/h) of the vehicle, a real-time speed and flow graph of the last 24 hours, and traffic congestion levels by color. Users can search for traffic information by location, region, or road name. The app also displays public restroom and drinking water locations and offers a travel time interface.

One of the best features of Thailand Highway Traffic is that it provides accurate traffic data provided by the Bureau of Highway Safety, Department of Highways (DOH). With this app, users can easily monitor the traffic situation on the highways, plan their trips accordingly, and avoid congested areas. The app's interface is user-friendly and easy to navigate, making it a great tool for both locals and tourists in Thailand.
