[sumo-user] update of travel time

[ali mirzaei <alimrz222@xxxxxxxxx>]

Hi everyone,

In the ~.alt.rou file of iteration i, there are two routes r and s. In the next iteration, the r route is chosen and in ~.alt.rou of iteration i+1, we will update the travel time of these routes. According to what Gawron says, for not remembering the routes which have not used for a long time, the updated travel time of the route s will be: 

I want to know:

1- The difference between the underlined variables.

2- The meaning of "how long". Does is it refer to any specific number of iterations? 

Best regards,

Ali
