Traffic analysis statatistics
Traffic analysis statatistics
(OP)
Hello everyone,
new to the forum and traffic engineering in general. I was hoping for a point in the right direction with a traffic study problem.
I have automatic traffic counter data for for a 2-way road. I am seeing if a pedestrian crosswalk is warranted at the location.
My output data from the traffic counter is arranged by the quantity and length between vehicle gaps occurring over each one hour counter interval for 24 hours. I am trying to figure out the average wait time for a pedestrian that needs a full 9 seconds to safely cross the road during peak hour.
Thanks,
Chris

BTW, in California, pedestrians have the right of way regardless of the existence of a crosswalk.

Your counter data presumably has each occurrence tied to time. Are the two directions separately tallied?

Is this in a state in the US?

It's a little stale now, but the seminal research paper on uncontrolled (no signal or stop signs on the vehiclular approaches) crossings found:
The authors recommend more than just preformed tape across the road if you want to make it safer. Actuated signals or beacons and raised median refuges were recommended.
@Goober Dave, considering his units, he's probably in the US. I believe we're the only country using that archaic measuring system other than Liberia and Myanmar.

1.Highlight all gaps 9 seconds or greater. (crossing potential)
2.Calculate each time segment between THESE gaps. (waiting periods)
3.Compute statistics on the waiting periods. (This should give the average waiting time you were seeking in original post).
It should be easy to do in a spreadsheet.

I pretty much did the steps that Terryscan mentioned. I got an average peak pm wait time of 45 seconds. Not too good for pedestrian patience I suppose.
