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
