Abstract :
Mastrip Highway, Jombang Regency, East Java, is now the main road for heavy vehicles after a change in road function. With the change in road function, the volume of vehicles on Mastrip Highway increases. Because the increasing number of vehicles on the highway will cause traffic jams that can affect the quality of road services. To ensure the smooth running of the road as expected, it is necessary to improve the road. This data collection used the 2014 PKJI method. The survey was conducted over three days during peak hours. From the results of the research conducted, the degree of saturation is 0.30, which means Jl Raya Mastrip is still working well, and it is known that the average volume of this road is 1,010.53 skr/hour.
