Thanks Barry. I tried to remove some routes that created traffic jams in the network due to U-turn, but it only reduces some traffic jams. It doesn't solve the jam in other parts of the network. I would like to know if there is any other way to generate and check the implausible routes. Is there a way to use implausibleRoute.py with routeSampler to improve the traffic flow?
