Re: [sumo-user] Assign Polygon as Parking lot in SUMO-TraCI

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

If you wish to treat your parkingArea as a black-box you can just specify  the desired capacity as roadsideCapacity. (no physical checks are performed).

Alternatively, you can compute the desired number of <space> definitions within a polygon boundary using tools/generateParkingLots.py

Hello,
I would like to create Parking lot using polygon option and treating it as a
black box instead of directly using Parking function in SUMO.
I have done coding for my parking lot(capacity, veh:entry, exit etc..) in
python. And separately created the parking spot using polygons in SUMO. Now
I would like to know how to assign this polygon as Parking space. ?



Attached is my code:


import os
import sys
import random


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
traci.init(9999)


#contains traci control loop

def run():
    step = 0
    vehicles=[]
    while traci.simulation.getMinExpectedNumber() > 0:
        traci.simulationStep()       
        print(step)
        vehicles= traci.vehicle.getIDList()
        step += 1
        print(*vehicles, sep = ", ")

        #parking lot
        floors=1
        slots_per_floor=3
        total_capacity= floors* slots_per_floor
        slot= [-1]*total_capacity
        available= 3
        occupied= 0
        slotid= 0
        def display_cars():
            print(*vehicles, sep = ", ")

        def available_spaces():
            print('The number of open spaces available are:')
            available = total_capacity - occupied
            print(available)

        def get_empty_slot():
            global slot
            for i in range(len(slot)):
                if slot[i]== -1:
                    return i

        def add_vehicle(vehicles):
            global occupied, total_capacity, slot
            if occupied < total_capacity:
                slotid= get_empty_slot()
                slot[slotid]= vehicles
                slotid= slotid+1
                print("vehicle is parked", vehicles, "slotid", slotid)
   #            traci.vehicle.setStop(vehicles, "e1", pos=38.0)
                occupied= occupied +1
                return slotid
            else:
                print("Slots not available")
                return -1

        def empty_slot(slotid,vehicles):
            global occupied, slot
            if occupied>0 and slot[slotid-1] != -1:
                slot[slotid-1] = -1
                occupied = occupied - 1
    #            traci.vehicle.resume(vehicles)
                return True
            else:
                return False
        def status():
            print("slotno. \t vehicle id.")
            for i in range(len(slot)):
                if slot[i] != -1:
                    print( str(i+1)+ "\t\t" + str(slot[i]))


    traci.close()
    sys.stdout.flush()

#main entry point
