MYGHI and pHJKR comparison for succeeding criteria on sustainable road design and construction activities of road green tools

Abstract

Assessment of green road in Malaysia can be considered new throughout the country. There are two prominent sustainable rating tools for the road in Malaysia which are Malaysia Green Highway Index (MyGHI) and Penarafan Hijau JKR Sektor Jalan (pHJKR-KJ). Penarafan Hijau JKR (pHJKR) was developed by Malaysia Public Work Department (PWD), where it is a measurement tool to assess the sustainability level of government development projects, pHJKR help to promote the requirement in sustainable development within road works project. Whereas, Malaysia. Green Highway (MyGHI) Index assessment which has been introduced in 2015 by Malaysia Highway Authority (LLM), is focused more on sustainability degree assessment of Highway in Malaysia. However, it is found that some assessment criteria are only available in respective rating tools. The specific criteria is only available in pHJKR neither nor MyGHI. In terms of design and construction activities, pHJKR has 43 sub-criteria, while MyGHI has 10 sub-criteria, and 26 super sub-criteria. Even pHJKR cover larger sub-criteria in the assessment, but there are still some sub-criteria in MyGHI is not included in pHJKR. Hence, it is essential to study the comparison between pHJKR and MyGHI. Opinions from the user of MyGHI and pHJKR rating tools are collected thru matrix tabulation survey to measure their level of agreement of respondent on the relation between proposed criteria for succeeding green road rating tools. From the result of the survey, Relative Important Ratio (RIR) analysis was used to represent significant of the proposed criteria for succeeding green road rating tools. By reviewing the existing criteria in both road rating tools, it will lead to the identification of more relevant succeeding criteria into new future road rating tool, with this, any existing rating criteria can be incorporated, revised and improvised, to make it more sustainable and reliable in road project practice.
