Traffic Projection

Traffic Projection

Traffic Projection

A park with playgrounds (football, soccer, etc..) is being developed adjacent to the street I am designing. An intersection exists 1/4 mile ahead of the entrance to the park.. I am leaning towards a warrant study but my question is the traffic counts is for existing traffic and how would one project the future traffic? I am unable to obatin any design criteria from the people building the park.

RE: Traffic Projection

I agree with IR. You should be able to find a growth factor. Is there a local/county planning commission that can provide some general information? Do you know anyone who has done a project in that area? Or you could try your state DOT. They should have a factor that they would use for projects in that area. Keep in mind that GF's can very subjective.

I don't know if the AASHTO Green Book has any guidance on the subject. In bridge design AASHTO says assume a 3% GF for fatigue design if one isn't available.

RE: Traffic Projection

Will GF be sufficient? I am concerned if there is an event at the park.

RE: Traffic Projection

If there's an event at the park that would draw a large crowd, I assume that there would be traffic control agents.
