I just started adding pedestrians to my simulation and found that large numbers tended to get jammed at crosswalks. The green walkers are walking south, turn right to cross the street, then turn right again to walk north. In the process of turning north, some of them turn too sharply and end up waiting in the street at the stop line until they can shift left to get back to the side walk. If there are too many other (yellow) pedestrians coming from the opposite direction, the green ones can start accumulating in the street blocking traffic. Even with a low generation rate, a large number of walkers can accumulate at a red signal, and when they all cross at once, this problem occurs.
Here's the code I used to generate them:
<routes>
<personFlow id="CCW_person" begin="0" end="3600" probability="0.25" departPos="0" color="1,1,0">
<walk edges="j017-e3 j018+e1 j018-e1 j017+e3 j017-e3" arrivalPos="0" />
</personFlow>
<personFlow id="CW_person" begin="0" end="3600" probability="0.25" departPos="0" color="0,1,0">
<walk edges="j017+e3 j018-e1 j018+e1 j017-e3 j017+e3" arrivalPos="0" />
</personFlow>
</routes>
By the way, when I sent this message yesterday, the server refused it, saying the message was from the future!
