| Abstract | This research was an initial attempt to determine the understanding of traffic control devices commonly used in Thailand by a sample of motorists from several countries measurement of driver comprehension of traffic control devices was accomplished by using a multiple choice type of test consisting of 53 questions on a wide range of standard and a few non-standard devices. The traffic scenes were recorded on videotape of sites in and around Bangkok. Each sign, signal, or pavement marking appeared initially in a panoramic view, with subsequent zooming onto the device toward which attention was to be directed. the total duration for presentation of the 53 scenes, with time for respondents to mark their answer sheets was one hour. A total of 175 respondents were tested. The respondents were instructed to mark one answer (of the four substantive responses) per question which best described the legal intent of the device being considered. The legal meaning of each traffic-control device was taken as the correct response. For each question, "none of the above is correct" was provided as a fifth alternative response. The results of the observations were analysed by statistical techniques to fine the effect of difference by nationality, sex, age, possession of a valid driving license, driving experience, and driving frequency. The Null Hypothesis of no difference amongst nationality groups was rejected at the 5% level in both the analysis of variance and the Kruskal-wall is test. Subsequent analysis indicated that the Thai respondents were significantly superior to those from the Philippines and Indonesia. This finding was confirmed for both top-control and bottom-control analyses. The mean of all test scores was 63.3% of the traffic control devices understood by all respondents. Statistically significant differences were sound for licensed drivers as compared to practicing but unlicensed drivers. Driving experience of 5 years of more of more led to a significant difference, compared to less experienced respondents. At the 5% level of significance. Null Hypotheses were accepted for male vs. female respondents; for driving frequency (often of rarely drive). using the T-test, there was no significant difference (at 0.05) between male and female respondents. |
