Hello,
I'm trying to implement road traffic simulation where emergency vehicle is
overtaking other vehicles on the road.
First let me list the steps of simulation implementation:
1. At first I downloaded osm file of specific map area (e.g. Berlin)
from openstreetmap.org
2. Using *NETCONVERT* is map.osm file converted into map.net.xml
(command: *netconvert --osm-files map.osm -o map.net.xml*)
3. Using TraCI are generated random trips and started simulation (with
parameters: *--lateral-resolution 0.8*).
4. During simulation is added emergency vehicle:
-
*traci.vehicle.add(vehicle.id <http://vehicle.id>, vehicle.route_id) *
- *traci.vehicle.setVehicleClass(vehicle.id <http://vehicle.id>,
'emergency')*
-
*traci.vehicle.setSpeedFactor(vehicle.id <http://vehicle.id>, 1.5) *
- *traci.vehicle.setSpeedMode(vehicle.id <http://vehicle.id>, 0)*
- *traci.vehicle.setLateralAlignment(vehicle.id <http://vehicle.id>,
'left')*
5. At each step of the simulation, I check if any vehicle is in front of
emergency vehicle. If it is, I'm slowing it down (using:
traci.vehicle.slowDown(...))
6. The vehicle in front of the intervening vehicle is stopped and at the
moment it should have been overtaken. Only this does not happen and the
intervention vehicle stops as well.
I'm looking for any hint or idea why overtaking is not performed.
I also tried to use netconvert with parameter *--opposites.guess true*,
but the conversion failed because of error: *Opposite lane <lane_id>
(length x1) differs in length from edge <edge_id> (length x2)*.
Thank you in advance for your reply.
Best regards,
Luka
