Traffic congestion has contributed to economic loss and increased the number of traffic accidents. Previous studies have revealed that the land use pattern in Kuala Lumpur is dispersed and leads to traffic congestion. Thus, this study is to investigate the type of land use that affect the traffic congestion in Kuala Lumpur. The data in this study was collected by using 384 design questionnaires and analysed by using descriptive analysis. The results showed that the high proportion of commercial land use causes the highest level of traffic congestion. This study makes contributions as a reference for the students to gain knowledge on how traffic congestion is influenced by the land use pattern and appropriate land use planning such as mixed-land use or grid plan are important to reduce traffic congestion.

Johor is one of the states in Malaysia that records high accident statistics, especially on Federal Route FT050, Batu Pahat-Ayer Hitam. One of the elements causing an accident is the attitude of a driver who drives too fast and ignores the warning and speed limit signs. The study aimed to determine whether the warning signboard’s impact on driving speed at the before- and after-study locations. The GPS DG 200 was used to record the speed data of 50 trips at Batu Pahat to Ayer Hitam. Descriptive and inferential statistics (paired t-test) were used to determine whether or not a driver reduced their speed when approaching an accident-prone area. The results indicate that the warning sign is significant because drivers reduce their speed after passing a warning signboard.
