Abstract: 
Traffic congestion is a problem that many face; the aim in this project is to design traffic lights that reduce the traffic congestion. The idea is to have the driver make little or no stops at traffic lights, by having him move at a constant speed. Three main intersections were selected for this type of design. At each intersection, the vehicles were counted to obtain the vehicles per hour; these values will be used to obtain the flow numbers for each intersection. With the flow numbers calculated, the green time and therefore the cycle time for each intersection are obtained; including the configuration for each cycle. However, the most important part here was selecting the sequence of the phases to reduce the delays as much as possible. This will all be done using the Webster method. The results were very promising, showing an optimum cycle time to use for each intersection. Also, the delays for each intersection were as hoped; that is, there were no delays. By designing the traffic lights this way, we reduce the risk of: accidents, environmental impact, economic impact and most importantly due to minimal delays; the traffic light congestion. We concluded that the HCM method cannot be used in our case.
