Thailand loses about 25,000 people every year to road trauma: this motivated this study, which designed and evaluated a simple system to discourage ‘Red Light Running’ – failure to observe red traffic lights. Our system is simple, cheap and flexible – consisting of a single camera, a portable computer and the ability to send images to a mobile phone using the public network. However, to be flexible, cameras were set only 1-2m about the road, which caused many occlusions to be observed – the major challenge for the system software. A rule-based system was used to resolve most occlusions. In our tests, vehicles were completely and correctly tracked in 83% of frames. This was sufficient to allow images of 95% of Red Light Runners to be transmitted to a monitoring station and potentially stopped.Thailand loses about 25,000 people every year to road trauma: this motivated this study, which designed and evaluated a simple system to discourage ‘Red Light Running’ – failure to observe red traffic lights.
