: The stream of traffic movement within the weaving section doesn't only have an effect on freeways but 
additionally affects urban roads. The important aim of this paper is to check the two-sided weaving section on urban 
roads because the previous model by HCM (Highway Capacity Manual) sixth Edition 2016 was targeted only at 
studying the weaving section on highways. Three selected two-sided weaving section sites were chosen to capture 
different traffic conditions and are utilized in a simulation model by the Vissim software system to calculate the 
level of service (LOS). After that, the obtained results from the calibrated and validated models of every site would 
be compared to the LOS generated by the HCM equation for a similar. This paper shows that HCM provides a 
similar LOS and nearly a similar density compared thereto obtained through simulation at the values V/C (Volume 
per capacity) equals 0.44. For the weaving section with V/C values of 0.63 & 0.93, there was a major distinction 
between the LOS and density results obtained from the simulation model rather than HCM manual methodology.
