Re: [sumo-user] Reducing transit traffic through an edge

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Vehicle routing finds the fast route given some assumption about travel speeds on each edge.

To discourage edges for transit you can either

- lower their speed limit (which affects all vehicles that travel there) - this can be done efficiently in netedit by selecting all roads of a particular type and setting the speeds all at once.

- lower the assumed routing speed (which only affects routes of vehicles that have a choice but keeps actual driving speed unchanged).

If you compute your routes ahead of the simulation with duarouter, you may simply provide an edge weight file to set custom travel times for each edge

If you compute your routes within the simulation, see https://sumo.dlr.de/docs/Simulation/Routing.html#travel-time_values_for_routing

Jakob

Hello fellow sumo-users,

I wonder, if there is a way to reduce transit traffic on certain edges, to make them drivable mostly for cars that have their destinations here, but at the same time, not to cut it off for transiting completely?

The reason I ask is that I notice, that some drivers go from one congested secondary street to another, also with dense traffic, through service communications and then get stuck when trying to enter main street, so they block service roads for those who actually need to be there. Simplified, it looks as shown below:

If no instrument to restrict transiting exist, how do I forbid it? Every type of road has its own max speed.

Regards,
Dmitrii Grishchuk.
