Mathematicians Have Solved Traffic Jams, And They’re Begging Cities to Listen

Sick of traffic? Me too.

It’s the mathematicians vs. engineers.

1. All drivers need to be on the same navigation system. Cars can only be efficiently rerouted if instructions come from one center hub. One navigation system rerouting some drivers does not solve traffic jams.

2. Parking bans. Many urban roads are too narrow and cannot be physically widened. Traffic-flow models can indicate where parking spots should be turned into lanes.

3. Green lanes. For cities that want to increase electric car use, special lanes should be created for electric cars, providing an incentive for their use.

4. Digital twins. Traffic demands and available infrastructure can only be balanced with digital modeling that creates an entire “twin” of existing roadways. The software will be “an extremely useful thought tool in the hands of transport engineers.”
