ABSTRACT

It has been man’s effort to minimise human intervention and automate procedures. This has been applied in controlling traffic too. At times we would’ve noticed sparsely populated lanes and highly populated lanes having the same amount of signal duration for movement of vehicles. We cannot have a one-size that fits all policy. The simple rule of thumb to overcome this problem was to accord a higher priority and more time to lanes having higher vehicle density. Keeping this in mind we have designed a traffic scheduling algorithm which allocates signal durations based on the traffic density of individual lanes. We determine the vehicular density up till a threshold distance in every lane and then accord priorities and proportionate signal durations. Our algorithm accounts for the real-time change in vehicular density. This is done in a round-robin fashion to prevent starvation problems in the algorithm.
