Abstract


This research discusses the relation between Travel Time and Degree of Saturation for the urban road
links, especially for the city of Semarang, by using regression method which Travel Time as a
polynomial function of Degree of Saturation.
Siliwangi Street and Soekarno-Hatta Street are selected as the sample for arterial road, Thamrin
Street and Supriyadi Street as the sample for collector road, and Lampersari Street and Ksatrian
Street as the sample for local road. The research found the general formula for Travel Time and
Degree of Saturation relationship for the urban road links as : W = wl [ 1 + a ( DS )4 ] , where the W is
the travel time, the wl is the travel time at the free flow and the DS is the degree of saturation.
It is also found that the arterial road wl = 6,5 – 6,75 second and a = 0,15 – 0,4 , collector road gives
wl = 8,25 – 8,9 second and a = 0,4 – 0,6 and local road, gives wl = 9,62 – 11,93 second and a = 0,3 –
0,4.
The research has shown that the travel time and degree of saturation relation model for arterial road
was exactly similar to the Indonesian Highway Capacity Manual (IHCM ), 1997 standard, but for both
of collector road and local road were not in the same condition. It means that in this case the
Indonesian Highway Capacity Manual ( IHCM ), 1997 standard was only able to be used for arterial
road. It is not recommended to use the Indonesian Highway Capacity Manual ( IHCM ), 1997
standard for collector road and local road.
