Evaluation of side friction in IHCM for highway 4 lanes 2 ways divided

Abstract

IHCM (Indonesia Highway Capacity Manual) was issued and came into force in 1997. After 20 years there has been a change in traffic from the number and composition, as well as the traffic regulation policy. As a result of this, the determination of IHCM's road capacity is often incorrect. Therefore it is necessary to evaluate IHCM. This study tries to evaluate IHCM through side friction factors, as one of the factors that determine the value of road capacity. Research is limited to evaluating the weight of each side friction factor and the effect of land use from the survey results using statistical analysis. From the analysis, it is found that the conditions for the use of shops, office and campus are in the category of high and low of side friction factor and the ranking of the relative weights of the side friction factors in IHCM is quite different.
