UiTM study on road signs in Malaysia: The impact of information volume of road sign on level of visibility
نویسندگان
چکیده
This study was to investigate the information volume of road sign and level of visibility using real road sign. Five road signs of 5and 10-letter word combinations were shown randomly to the subject for 2 to 3 seconds at 30 meters initially. The road sign was moved closer to subject, 1 meter at a time until the subject saw the road sign correctly. The distance of first correct response demonstrated the minimum distance any of the road signs was visible, while distance of all correct response indicated all the road signs can be recognized. Paired t-test showed that the difference in the distance of first correct response between the 5-letter and 10-letter word combinations road sign was statistically significant (p < 0.05), but no statistically significant difference in the distance of all correct response (p > 0.05). The information volume could affect the level of visibility of the road sign to a certain extent.

متن کاملHow Drivers Understand Safe Behaviour and Perceive Risks at Passive Railway-Road Level Crossings
This study was designed to investigate how drivers assess safety issues at passive railway-road level crossings. The study was limited to traditional and relatively inexpensive safety measures. Fifty-six car and van drivers were interviewed after passive level crossings with low traffic volume. Both key requirements of safe behaviour (i.e. decrease of speed and looking for trains) were indicate...
