For Indonesia cities, walking mode, is not yet preferred one because of lack of walking facilities. Walking assessment is needed to evaluate how the walking infrastructure and environment can encourage more walking. The research objective is to develop is walkability measures using the concept of walkability index with case of Bandung city. The index was considered as the quality parameter of walking facilities for ease to walk. Four city areas were used with nine parameters to assess the index. Based on the parameters, a scoring system was developed and to complete it, a survey form was developed and then filled up as an inventory survey along the dominants walking routes within theoretical catchment area of 800 meters from the center area. Research findings show that index for the study areas spread was relatively same. However, detail investigations on the index's parameters showed that were critical condition for walking facilities improvement.

The necessity of shifting the policy focus from supply-side initiatives such as physical-capacity expansion to demand-side initiatives including ease of congestion is newly rising as a compelling method of improving the general ride quality of the metro users. In an effort to catch up with such shifting trend, a system schematic that will update the congestion status of the metro lines via mobile devices is suggested through this study, along with the development of a smartphone application to realize this service idea. The developed smartphone application allows the metro passengers to identify the congested area of each station platform and to receive information on the congestion level of each train and car. Through such assistance, the metro congestion information system can improve the overall convenience of the metro passengers by helping them identify the congestion level across the metro lines.

A study using permeability as the main parameter was performed to examine the drainage and clogging behaviors of different pervious concrete mixes used for pavement construction. This paper presents the findings of the clogging performance of the pervious concrete mixes against possible clogging materials found in Singapore roads. Clogging was created by introducing clogging materials progressively into the pervious concrete tested. A constant-head test was used to determine the permeability of the pervious concrete at different stages of the clogging test, and the clogging performance was determined by monitoring the reductions in permeability as clogging developed. The clogging potentials of different pervious concrete mixtures are represented and compared in terms of the deterioration trends of their respective permeability as the clogging process progresses.

This paper investigates the effects of road hump on traffic volume and noise level in a residential area in Kuala Lumpur. Field surveys were administered to measure data on traffic volume and noise level at three selected roads at Taman Keramat residential area in Kuala Lumpur. Measurement on noise levels such as LAeq, LAFmax, and LAFmin and traffic volume were undertaken for about 12 hours. The findings show that the highest traffic volume (563 vehicles per hour) and the highest noise level (75dB(A)) was measured at Road 1. The correlation analysis indicates a similar pattern in the relationship between traffic volume and noise level especially at Road 2 and Road 3. Finally, this paper concludes in drawing attention to conduct further studies on the effects of road humps in other residential areas in Kuala Lumpur to implement measures for a pleasant, harmonious and safe living environment for the community.

Factors influencing poly-centric employment formation in metropolitan regions are identified and explained. Less is known about the dynamics of change in cities of the developing world so a comparative study was proposed that was successfully funded by EASTS International Collaborative Research Activity (ICRA). A common analytical framework is outlined. This paper presents preliminary empirical findings for rank-size distributions of employment and for employment specific preference functions for the journey from work to home. Comparative findings are presented and interpreted for Bangkok, Canberra, Dalian, Delhi, Istanbul, Sapporo, Sydney, and Tokyo. Directions for on-going research are outlined.
