how can we model leading pedestrian interval (LPI) in synchro? suppose i would like to provide 4 seconds of LPI, how would i do that in synchro? Thanks.

Hi,

My thought is that you might have to code in a dummy phase to start up as the same time as your ped leading phase. Overall, this will make your split 4 seconds longer.

Good luck,

Thanks MT. How would i code dummy phase?

Wouldn't adjusting your all-red intervals accomplish the same thing? Bump those up 4 seconds, and it should be the same impact on vehicular traffic. I don't think you'd be able to code an early start for the waiting peds though, but I'm guessing you're mainly looking at the impacts to traffic.

upretys,

Please see the attached example. This is one way of doing it.
