The increasing number of vehicles along local roads in many residential areas has created unconducive environment and safety risk due to the increase in the speed passing vehicles. To control the speed of the vehicles, road humps were installed along local roads. This paper evaluates the effects of road humps on the speed of vehicles in Taman Setiawangsa, which is one of the residential areas in Kuala Lumpur. The field observational survey was carried out to collect data on design characteristics of the road humps. A spot speed survey was administered to collect spot speed of vehicles at different points near the road humps and the spot speed data at and near road humps were analysed using measures such as descriptive statistics and dependent t-Test. The design characteristics of the road humps were also compared with the existing road hump guidelines published by the authorities. The major finding of this study depicts the effectiveness of road humps in reducing speed in relation to the road hump’s profiles.

Road is an infrastructure that built to support the movement of the vehicle from one place to another for different purposes. Today, it is often found damage to road infrastructure, both local roads, and arterial roads. Therefore, to keep the pavement condition to remain reliable, in Indonesia has a periodic program by conducting an objective functional inspection of roads regulated by Bina Marga using the International Roughness Index (IRI). However, the IRI examination is not sufficient to represent the actual field condition; it is necessary to perform subjective functional examination by appraising the road one of them is Pavement Condition Index (PCI, ASTM D 6433). This method has been widely applied in some countries because it has many advantages. However, to do this inspection requires considerable cost, then there needs to be a model to get the relationship between these two parameters of the road. The selected case study was arterial road segment in Medan City, that is in Medan inner ring road. Based on the results of the analysis, there is a difference between the functional conditions of PCI and IRI. The equation derived from these two parameters is by exponential regression equation, with equation IRI = 16.07exp-0.26PCI. with R2 of 59% with correlation coefficient value (r) of -0.768. The value of R2 indicates that PCI gives a strong influence on IRI value.

Maintenance Work

Radar speed signs (RSSs) are a measure for reducing traffic flow speeds through work zones. The influence of truck-mounted RSSs on vehicle speed was evaluated for mobile maintenance operations in two multilane maintenance work zones in Oregon. In each case study, two periods of testing were conducted: one with the RSS display turned on (treatment) and one without the RSS display turned on (control), and vehicle speeds were recorded. Descriptive statistics were used to summarize collected data, and a two-sample t-test was applied to each case study to compare the speed difference between control and treatment cases. The findings indicate that vehicle speeds are typically lower and that there is less variation in speeds between adjacent vehicles with the RSS turned on. RSSs are thus promising devices for controlling vehicle speed and making work zones safer for motorists and workers.

The Relationship

In recent times, residential districts in modern cities face certain new and undesired problems related to antisocial behaviour by adolescents in its urban public spaces. In this study, we investigate the relationship between the design features of public spaces in residential areas and the problem of vandalism within the districts. This paper examines the current literature reviews on vandalism, the main reasons behind the increase of in the problem, types of vandalism, and a mathematical model for assessing visibility and accessibility in addition to proving the results of a field study conducted in a UAE city. We believe that visibility of vandalism-prone areas through dwelling windows, accessibility of such areas by residents through dwelling entrances, and recognition of ownership of such areas can definitely play a role in mitigating vandalism. Our findings indicated the following: (1) There is a strong relationship between vandalism and visibility through dwelling windows. (2) Residents' accessibility to dwelling entrances and recognition of ownership play an important role in reducing vandalism. (3) In areas where the visibility and accessibility by residents is low, the severity of the problem of vandalism increase if there is an increase in the percentage of adolescent residents. (4) The design characteristics of the housing areas, such as the height of the blocks or the limits of public spaces, do not have any influence on the occurrence of vandalism.

Test Result

We present a mobile-based navigation system with the emphasis on the pedestrian navigation for Hospital Kuala Lumpur (henceforth, HKL) named as HKLNS. This practical research aimed to provide support and help for the people who come to the HKL. Despite having signages, layouts and other types of guidance to help them navigate, they might not be sure their current location and the destination’s paths. By using the OpenStreetMap (OSM) and Graphhopper API as a solution, it managed to help people to navigate the surrounding of the HKL. The findings showed that users were able to know their current location and the system generated the shortest pedestrian paths to the desired location using both mappings. The functionality testing and experimental results surrounding HKL demonstrated the effectiveness of this approach. The HKLNS was reliable based on the functionality and validation testing conducted towards 5 respondents with 5 different case study, in which it manage to reduce more than 50% time taken with the t-test result of 0.00041 (p0.05), indicated that the system was accepted.

Progressive increase in the influx of privately owned vehicles and a decrease in the modal share of public transport over the years become a city-based phenomenon. Over-dependence on cars encouraged a sedentary lifestyle, an obesity epidemic, social exclusion and increased carbon footprint. Deficiencies in urban planning have created a spatial separation between employment centres and residential areas. The research focused on investigating how people construct the meaning attributed to commuting mode of travel to work. Using multiple embedded case study research approach, this research focuses on 19 semistructured interviews with employees from two neighbouring but contrasting case study areas of Kuala Lumpur. Synthesis of the employees’ experiences on their travel behaviour exposed replication logic on the way they perceived walking as part of the transportation mode of travelling to work. The implicit understanding of the walking to work includes; definition of walking to work by the communities, specific walking stages and its’ characteristic during am-pm rush hours, the travel pattern and modes of transportation from the origin point (home) to the office, and the understanding of walking benefits to their economy, environment, health and social. These results provide possibility of understanding the needs of people and to promote walking to work as part of transportation mode for commuting in order to overcome the current urban challenges.

 The national statistics indicates that red light violations (RLV) have become a significant safety problem throughout the nation. As a result, the Malaysian government has initiated the installation of automated enforcement system (AES) to reduce RLV related crashes at identified critical locations particularly in Kuala Lumpur region. The primary aim of this study was to evaluate the effectiveness of AES installation in reducing RLR at signalised intersections using a case study at Jalan Ipoh, Kuala Lumpur. Before and after AES installation data were collected and were analysed using a statistical tool. T-test results indicated that the installation of AES has significantly reduced RLV behaviours at the studied signalised intersection. The results of this study provide a useful insight on the benefits of AES in decreasing intersection related crashes by means of reducing RLV behaviours among the road users through AES installation.
