Traffic volume, noise level, and speed level were the variables selected to measure the traffic living environment. Questionnaires were used to evaluate the residents' perceptions regarding their living environment. Field surveys were administered to collect data on traffic volume, noise and speed levels at the three selected roads. Measurement on noise levels such as LAeq, LAFmax, and LAFmin and the traffic volume were undertaken for about 12 hours, while the speed levels were recorded during the morning and afternoon sessions. In addition, 328 questionnaires were distributed at the residential area, and 187 usable responses were received. The findings show that the highest traffic volume (563 vehicles per hour) and the highest noise level (75.6 dB(A)) were measured at Road 1. The 85th percentile speed of the vehicles after passing the road hump was slightly higher than the posted speed limit with speed of 32km/h (in the morning) and 31km/h (in the afternoon). For Road 2, there were more vehicles on the road in the afternoon compared to the morning, and the highest noise level recorded was 70 dB(A). The 85th percentile speed of the vehicles was from 23 to 24 km/h when approaching and passing the road hump. While Road 3 has indicated the highest average speed before and after the road hump (morning and afternoon session) and the highest noise level recorded was 72.9 dB(A). The 85th percentile speed of the vehicles when approaching and passing the road hump was 35 km/h and 34 km/h, respectively. In addition, the result from the questionnaire survey shows that 35.8 per cent of the respondents were extremely dissatisfied with the traffic volume at major roads, and the highest dissatisfaction came from the residents living in the flat and terrace type of houses. Vehicles passing along the roads made more noises compared to the noise of braking and accelerating after the road humps. However, most of the respondents were satisfied with the current noise level. About 32 per cent of the respondents were also found to be dissatisfied with the overall speed at the residential roads, and the use of road humps did not seem to slow down the speed of the vehicles. Overall, the residents were satisfied with the current living condition although the traffic volume and speed level were the major problems concerning a healthy living environment. This has contradicted the findings of the fieldwork survey, where noise level was found to be the main source of problem due to increase in noise level above the permissible noise limit in the residential area. Finally, this research recommends for further research to be conducted on the effects of road hump on the living conditions in other residential areas in Kuala Lumpur. This study also suggests on how to implement appropriate measures for a pleasant, harmonious and safe living environment for the community.
