THE INFLUENCE OF MOTORCYCLE ON THE CAPACITY OF TWO LANE TWO WAY UNDIVIDED URBAN ROAD LINKS IN DENPASAR, BALI
Abstract: The proportion of
motorcycle in Denpasar city is accounted for by more than 85%. This indicated
that motorcycle dominated traffic flows inDenpasar city. Three types of
vehicles consisting motorcycle, heavy and light vehicles make up such a mixed
traffic condition. This certainly is potential tocreate traffic problems
involving road capacity reduction. This study investigates the effect of
motorcycle on capacity of two lane two way undividedurban roads in Denpasar
city. Linear regression models were developed for twoseparate locations
consisting mid blocks of Ahmad Yani Road and Hayam Wuruk Road. The motorcycle
percentage on Ahmad Yani Road is less scattered than that on Hayam Wuruk Road.
Therefore, the relationship between road capacity and motorcycle percentages on
Hayam Wuruk Road (R2 = 0.46) is lesssignificant than that on Ahmad Yani Road
(R2 = 0.78). Both locations however,suggest the same results. This study found
that road capacity decreases as the percentage of motorcycle in the traffic
stream increases. The motorcycleequivalent unit (MEU) therefore, is suggested
for future study to convert such a mixed traffic condition into a homogeneous
condition.
