Hi Michael, Thank you for your answer.
My simple test network is a gridnetwork, all the edges have same types, no intersection has traffic lights - all of them working by "priority" method. So every component have the same details. I checked the routes visualy in GUI by "show current route". When there is no reroute device, first car makes loops and many unnecesarry ways. It dosen't use neither shortest nor fastest route. When there is reroute device, first car goes directly to the aim on the shortest route. Screenshots can see here: https://drive.google.com/drive/folders/0B2MSsuw0vMlzTTZKOTctWjlobHc?usp=sharing I tried on other gridnetworks, but all have the same situation. I tried to ran duarouter using code "--remove-loops true", but nothing happend. Do you have any idea in my case why duarouter working on a really not effective route? How can i use it properly, maybe on gridnetwork doesn't work? thank you, Adam 2017-04-21 18:40 GMT+02:00 Michael Behrisch <[email protected]> : > Hi Adam, > duarouter is not looking for the shortest route but for the fastest > (without considering traffic delays), so you may have (theoretically) > fast roads in your network, like motorways, which get jammed when > running the simulation, delaying the car.
