Intelligent Traffic Signs in Thailand provides real time
travel information to the people who are travelling on the
roads in Bangkok. Detector Camera and Occupancy Ratio
(OR) techniques are used to calculate and determine the
density of the ahead route. The information is shown on a
screen next to or over the road, and also on the website
BKKTraffic.com. However, thissystemdoes not communicate
with cars on the road at the moment which is an interesting
possibility for development in the future [41].
