The Green Ripple Effect
Floor Location : M 105 N
Every year, the average american driver spends almost 300 hours on the road, 59 of which are just spent on waiting at red lights. In the 1950s, a traffic light system known as the “green wave” had been used to optimize traffic flow. However, as cities experienced exponential growth over the past few decades, the green wave system could no longer keep up with rapidly changing urban infrastructure.
In this project, I developed and tested an upgraded version of the green wave, named the “green ripple”, which I adapted to fit into modern cities. I hypothesised that road systems with traffic lights operating on the green ripple will decrease overall traffic congestion.
I created a simulated city where I implemented, tested and compared the overall efficiencies of the green ripple against the current standard traffic light system. In all comparisons, the green ripple was able to surpass the traditional algorithm on all four tested categories: average time for cars to reach their destination, longest time taken for a car to reach its destination, shortest time taken for a car to reach its destination, and average time spent waiting at red lights. Thus, I was able to successfully design and demonstrate a novel traffic light control system that would optimize modern urban traffic.
