Hi, I am wondering if someone has some pointers to references on individual vehicle (or two vehicles) entry speeds into an intersection / junction and the likelihood of a collision. I imagine such relationships would vary by type of control, e.g. give way sign, traffic signal roundabout. Any ideas?
Something like that is already available for individual vehicle speeds/speeding in general context (Kloenden curves), but I am not aware of intersection-specific research. Anything from micro-simulation?
Dear Sir,
kindly refer these link.

Many thanks. Great documents authored by my friends! I am looking for basic research. Refining my earlier question, the research could be on:
a) approach speed distribution vs. crash probability/frequency
b) approach speed distribution vs. impact speed distribution
Any ideas where to look?
Do the following help?

Many thanks for pointing out gap acceptance research. Likely to have some good inputs.
Hi guys, got my answer today from TomTom. They have individual vehicle GPS traces across intersections (pinging to satellite every second). I should be able to get my hands on the speed distributions. This will give me entry, traversing and exit speeds across all intersection conflict points.
That is not the same as impact speeds, but a very good start indeed!
