Abstract
The traffic movement in the weaving section is not only affecting the highways, but also is affecting the urban roads. This kind of movement affects three aspects; the density, the
capacity and the speed of the traffic. This model is being established as the HCM 6 TH Edition (TRB 2016) mainly tackled the weaving section in the freeway but it didn’t address the urban
roads, accordingly we are going to study the urban road’s weaving section to be able to
compare it to the HCM. The study will focus on the two-sided weaving section, where the entry ramp is from one side whilst the exit ramp is on the other side of the road. Three sites
were chosen to measure different traffic conditions, in order to construct traffic simulation model to calculate the level of service of two-sided weaving section. The collected data were
used to calculate and validate the traffic simulation model to reflect the real situation. The
data consists of traffic data and geometry data. The traffic data were collected from a video
during the peak hours of the day, calculating speed, volume and lane change. Based on the
geometry data collected from the field weaving length, lane width, entry ramp width and exit ramp width were obtained. Three models were constructed, one for each site, via VISSIM, visual basic was used for simulating multiple runs to try different parameters for calibration
purposes. A model parameter set was concluded from the three previous models to fit all traffic conditions. Based on that concluded model. A compression was made between the level of service obtained from the developed model and the level of service generated by the
HCM (TRB 2016) equations. it has been noticed that HCM (TRB 2016) methodology can be used to analysis the weaving section on urban road when V/C ration equal 0.44 where the result almost the same. While it is not recommended to use HCM methodology to analysis
the weaving section on urban roads when V/C equal values (0.63 & 0.93) because there is a significant difference between the results. Also, it is recommended for future researches a
comparison is required between the simulation and HCM (TRB 2016) equations with different values of V/C.
