[sumo-user] Modelling two bus lines of equal frequency

[Jaime Moya <eljaimo@xxxxxxxxx>]

Hi,

I am modelling two bus lines of equal frequency, but different stop times at bus stops. To avoid buses being inserted at perfect regular times, I am using probability:

<flow id="517" type="vehDist_IDM_bus" line="517" begin="0.00" route="Ruta_517" end="4500" probability="0.0015" />
<flow id="518" type="vehDist_IDM_bus" line="518" begin="0.00" route="Ruta_518" end="4500" probability="0.0015" />

However, in many scenarios I am obtaining big differences in the number of simulated buses of one line with respect to the other (line 517 vs line 518). For example, the following graph shows the difference (number of 517 buses minus number of 518 buses) for a number of simulated scenarios:

These differences are important because I am getting results with noise. I don't want to use "vehsPerHour" or "number" because the buses would be equally spaced. Should I use period [exp(x)]? Doing so would balance the number of 517 and 518 simulated buses?

Thanks in advance.

Kind regards,
