Benefit Evaluation Of Road Rehabilitation At Nine Provinces In Indonesia

Abstract

All of project development needs to be evaluated howfar that project gives benefit. Benefit of a project can be form direct benefit or indirect benefit. Road rehabilitation is an action to improve road performance. As result of road rehabilitation is increasing of IRI, road capacity, actual road design speed, and direct benefit rehabilitation have the shape of reduce of Vehicle Operating Cost (VOC), reduce in travel time and eficientcy on maintenance cost of the road. Indirect benefit of road rehabilitation has effect on physical, social, economic, environmental and spatial, as like economic increase, people welfare increase, works opportunities, population growth acceleration, migration growth, social statues increase, changes on product distribution of commodities, loading-unloading, regional development, land use distribution, wide land production especially for agriculture, and changes on accessibility level. This research takes road projects between 1990- 1998 in Bengkulu, South Sumatera, Lampung and West Java Provinces. Through direct observation on sample data and simple analysis by multiregression method, correlation method and comparative method between before and after condition of the road rehabilitation project, has result IRI changes up to 140% in average more than condition before rehabilitation, ADT increase 140%. For Lampung and Bengkulu up to 150% - 165%, West Java and Lampung increase 360%- 470%. This study also resulting the relation between Speed and IRI such as : Speed = -0,13443* IRI+ 49,71993 (R=0,98) Vehicle composition will changes also especially on car and utility, meanwhile truck and bus tend to decline. After rehabilitation VOC decrease 21-46% average, and BCR 4,38 with benefit around 30 billion rupiahs each link for periode 1990 to 2010. Beside of benefit, the road rehabilitation raise negative impact as like level of traffic accident, productive land for food and crops planted which changes to industrial, residential or other non-agriculture uses
