Our final project focused on improving traffic flow at the busy intersection of Lakeshore Drive and North Meridian Road in Tallahassee, Fla., to reduce drivers’ wait times. This intersection troubled drivers, especially those trying to go north on Lakeshore Drive. The steady flow of cars on North Meridian Road creates difficulties for Lakeshore Drive traffic attempting to merge or turn. This causes long lines of cars and delays, particularly during peak hours.
We aimed to help cars move through the area more efficiently without worsening traffic on North Meridian Road. We determined that adding a continuous green signal offered the best solution. We based this decision on traffic data showing high northbound volume in the afternoon, indicating the need for improved intersection navigation.
Our design featured one post with two arms—one directing southbound traffic on North Meridian Road and another controlling cars from Lakeshore Drive. The new light would not affect northbound traffic on North Meridian Road. This continuous green signal would allow cars from Lakeshore Drive to turn onto North Meridian Road more easily. This improvement would reduce wait times, prevent traffic buildup and create safer driving conditions.
We modified parts of the roadway to ensure proper function of the new signal. We assessed the stormwater drainage system’s capacity to handle any changes. We also planned clear signs and pavement markings to guide drivers through the new traffic patterns. Overall, our project aimed to help people navigate this intersection more quickly and easily.
