Is there any way to code pedestrian movements such that they only cross one approach at a time (i.e., peds cross the NB leg, then wait on a refuge island while the SB traffic going, then cross the SB leg once the SB traffic has a red signal)??? I assume this could be done if the NB and SB lanes were coded as separate links, but I was wondering if it could be done when coding the two directions on just one link.

Thanks,
Andy

Hi Andy,

I am afraid there is no way to do this. Actually, even the solution that you suggest could have problems. If you coded the roads as parallel, you could get peds to cross one link. However, once they cross the link say toward the median, they will then disappear since they've reached the destination. Others may be generated to cross the other link, but it would not be the same vehicle.

Thanks,

John.

I had a similar situation a few months ago. I had a boulevard with a 50 ft. median modelled as 2 parallel links. The minor road used a 2-stage pedestrian crossing. We also successfully modelled a pedestrian overlap (by adding a pseudo-phase to a 3rd ring) on a portion of the crosswalk that didn't interfere with a pt/pm left turn phase on the minor arterial (we had to model this as the high volume of pedestrians impacted RTOR vehicles on the boulevard).

In my scenario, the high volume of pedestrians (700/hr) modelled well on a 2-stage pedestrian crossing. The only minor drawback was LT vehicles off the boulevard getting stuck occaisionally on the short link that separates the boulevard (2 parallel links).
