Abstract
Abdullah SilondaeRoad is a type of 4 lane 2 undivided road (4/2 UD)which is a pathway to urban activities, education, trade and. Theresearch objective is to model the relationship of trafficcharacteristic parameters on the Abdullah Silondae Road sectionbased on traffic studies, including studio volumes and vehicle speedswhich are classified into three groups namely motorcycles (MC), lightvehicles (LV) and heavy vehicles (HV).The variables used are traffic characteristics, namely volume, speed,and density. To determine the formulation of the characteristicsrelationship, three models are used, among others Greensield,Greenberg, and Underwood.From the results of the study concludedthat the Greenshield model is the best model with the value of R ² =0.99 with a mathematical equation the relationship of speed-density,volume-density, and volume-speed as follows: S = 41,3 -0,15.D, V =41,3.D-0,15.D², V = 273 . S – 6,6.S².
