: 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.
