Re: [sumo-user] Creating dynamic roadblocks

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

- vehicle angle is not taken into account to determine road space occupancy

- using the default model, each vehicle will only ever block one lane so you need to use 'dummy' vehicles to close additional lanes

- if a long vehicle is stopped on an intersection it will block cross-traffic according to it's length

- using the sublane model, a vehicle may close multiple lanes. Partial blockage is also possible so that a motorcycle can squeeze through will a passenger car cannot. Since the vehicle angle is not taken into account you have to artificially increase the vehicle width to block a wider area. Even a wide vehicle can block at most two lanes fully.  Using the sublane modle comes at a price in execution speed. See https://sumo.dlr.de/wiki/Simulation/SublaneModel

Hi all,
I am using Sumo via libsumo/C++ (and TraCI/Python for testing) as a traffic
generator in a simulation environment that has a human in the loop.

I would like to be able to create roadblocks while the simulation is
running, for example a stationary truck that is placed diagonally on two
lanes or in the middle of a junction. Other vehicles should stop or reroute
if possible. I am currently doing that by adding a vehicle and calling
moveToXY with the desired position and angle on every step. The problem is
that the roadblock / stationary vehicle blocks at most one lane, regardless
of the angle, type, width, etc. I guess it's because of the way Sumo
calculates intersections / collisions.

How would you recommend to achieve this functionality?

I read "How to simulate an accident" on the FAQ but I don't think it answers
my needs - I am already halting the vehicle, and closing a whole lane or
edge seems too much.

The only idea I could think of is to place additional "dummy" vehicles on
each lane that the roadblock should be blocking. But that will require
analyzing the road network, intersection the geometries and managing the
dummy vehicles. Is there a simpler way?

Thank you,
Shawn
