| Abstract | This research developed the conflicting study manual as a computer package to assist
in studying traffic conflict at an intersection. The required inputs of the developed package are
configuration and characteristics of the intersection such as number of approach lanes, signal
pattern, lane marking etc. While the outputs are the types and number of possible conflict
locations as well as the minimum sample sizes in term of conflict survey periods.
To demonstrate the application of the developed package as well as to examine the
effect of the traffic signal, two T-intersections of which one is signalized intersection and
another is non-signalized in Bangkok were selected.
It was found that number of conflicts at the signalized intersection were obviously less
than the non-signalized intersection. However, for left-turn movement conflict, results of the
findings showed that there is no significant (at 95% level) difference in the means of number
of conflicts of these two intersections. Thus, it can be concluded that although traffic signal
can minimize certain types of conflict, left-turn type of conflict is exempted. The main reason
may due to the fact that Thai motorists often disregarded and disobeyed the traffic signal
especially for left turning. They often slow down but did not completely stop and wait for
proper right-of-way. They may intrude other's privilege as such caused a high number of
conflicts as presented in this study |
