The first known attempt to control traffic with signal devices, over 150 years ago, did not end well. To manage the city’s growing volume of horse and buggy traffic, the London police used manually operated, gas-powered signal lights. Introduced in the 1980s and updated as the technology advanced, the Sydney Coordinated Adaptive Traffic System has been widely adopted to manage traffic signals across Australia. Adaptive control systems are expensive, but the fixed-plan systems they are replacing are not cost-free. Traffic control is a much studied subject, and as new technologies evolve and vehicles become smarter, intelligent adaptive control systems are likely to become the norm.
