Re: [sumo-user] Box topology of roads in SUMO

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

The paper states "Depending on the combination of the maximum lane speed and the input rate, the average number of vehicles in a simulation experiment ranged from45 cars/min to 402 cars/min, as described in Tab.I". 

- measuring "number of cars" in "cars/min" is a bit unclear

- the paper does not state the size of the network

- if you increase the size of the network more cars can enter

- If the grid size is > 2 then you will get traffic effects from the intersections. The network may jam and traffic flow can decrease over time

If you want to replicate that work, I recommend to ask the authors for the network file or at least more details on the way it was defined.

regards,

Jakob

Can you help me with the following
Specifications according to paper linked below:
Vehicle length = 5m, acceleration rate : 0.8m/sq.sec, decel rate : 4.5
m/sq.sec and max speed: 36m/s.
Box topology of roads using "netgenerate --grid --grid.length 1000"

trips created using randomTrips.py

For one of the simulation, maximum lane speed: 30m/s and Input rate :240
cars/min.

Even though I configure the simulation as shown above, I don't get average
vehicle density of 391(or any number near 390) as shown in TABLE 1 of
