Im looking for evaluating traffic safety at un signalized intersections by micro simulation. while reviewing related literature, I came across a term 'post-encroachment time'. So, I kindly ask for some related information.
Hi.
Your question can be answered by more carefully inspecting the literature.
Post-encroachment time is conventionally defined as the time between the first road user leaving the common spatial zone (in a 2 road user encounter) and the second road user arriving at it.
It is easier to understand its definition by looking at a figure. The attached publication (see reference) contains a figure, a discussion and further material to get you underway.
Hope this helps.

Article Evaluation of traffic safety, based on micro-level behaviour...
I have looked for a basic reference. However I only found the following: THE TRAUTENFELS STUDY
A diagnosis of road safety using the Dutch conflict observation
technique DOCTOR. You find it on http://www.swov.nl/rapport/R-85-53.pdf
It gives a reference to the basic development of the DOCTOR technique, which combines TTC and PET (Kraay et al 1986). I can not find that one though. May be you can look further.
My answer is similar to Floris Goerlandt. Sorry that I can't help you more.
thanks Mr. Goerlandt, Mr. Hayden and Mr. Hua .
So, while reading more literature, I came across one paper (Link: http://www.jtle.net/uploadfile/2014/0428/20140428034500296.pdf)
in this paper, there are certain parameter such as Class limit, Frequency which, agian, I didnt understand. So It would be helpful for me if anyone has some idea about these parameters. Thank you
