Re: [sumo-user] Pedestrian Collision in SUMO
Hi!
I have used the setSpeedMode(vehID, 30), but still the cars are stopping for pedestrians (even in green light) and no accident is happening. I have attached my source files herewith.
Can you please check if I am doing anything wrong?

import os,sys
import time

if 'SUMO_HOME' in os.environ:
    tools = os.path.join(os.environ['SUMO_HOME'], 'tools')
    sys.path.append(tools)
else:
    sys.exit("please declare environment variable 'SUMO_HOME'")

import traci
import traci.constants as tc

sumoCmd = ["sumo-gui", "-c", "ped_crossing/run.sumocfg", "--start"]
traci.start(sumoCmd)
step = 0
time.sleep(5)
while step < 100:
    traci.simulationStep()
    vehicles=traci.vehicle.getIDList()
    pedestrians = traci.person.getIDList()
    for vehicle in vehicles:
        speed = round(traci.vehicle.getSpeed(vehicle))
        pos = traci.vehicle.getPosition(vehicle)
        angle = traci.vehicle.getAngle(vehicle)
        traci.vehicle.setSpeedMode(vehicle,30)
    for pedestrian in pedestrians:
        speed = round(traci.person.getSpeed(pedestrian))
        print(speed)

    step = step + 1

traci.close()

Did you put jmDriveAfterRedTime=“1000” into the pedestrian type? For a working example. see https://github.com/eclipse/sumo/tree/master/tests/sumo/pedestrian_model/striping/block_vehicles/jaywalking_forward_collision

Note, that vehicles will always try to brake once a pedestrian violates a red light.
You could use set setSpeedMode(vehID, 30) to ignore the pedestians while still complying to traffic lights but you will have to mange not-crashing-into-the-leader-vehicle in your own code (vehicle.getLeader, vehicle.getFollowSpeed).

Hello!
I am trying to simulate collisions between pedestrian and vehicle in an intersection under the following assumptions:
  • The intersection will be traffic light regulated
  • The cars will follow the traffic light.
  • The pedestrian will not follow the traffic light and cross using the crosswalks whenever they reaches the crosswalk.
  • The cars will not stop or slow down for the pedestrians and hit them

First of all, I have tried to make the pedestrian violate the red light and use jmDriveAfterRedTime=“1000” in the *.rou.xml file, but still the pedestrians are stopping at the red light. For vehicle, I tried the TraCI speed mode, but if I set the mode to 0, they will also violate the traffic light, which I do not want.

So, in summary, Can anyone give me some pointers on:
  • How to make the pedestrians violate the red light and
  • How vehicles will hit pedestrian while following all other rules like red light, etc.

Regards,
Proyash
