摘要：Weaving is defined as a movement of vehicles that crossing over the direct traffic from on-ramp to off-ramp. Apparently, weaving maneuver lead to collision risk and weaving turbulence especially at twosided weaving section. The following study recognize the maximum weaving length and lane-changing rate on Federal Route 50 (FT050) segment. Visual recording technique was used at two different locations that are called as Site A (KM15) and Site B (KM16). Data of traffic volume was extracted by playback the video/personal computer. Analysis was made using spreadsheet and applied the methodology of the Highway Capacity Manual 2010. The study found that Site A has more tendencies to encounter longer weaving turbulence with maximum weaving length ranging from 1952 m to 2120 m, compared to site B that is 1866 m to 1882 m. Site A with a longer distance of weaving section 358 m has higher intense of total lane-changing rate that is 1142 lc/h compared to Site B with a distance of weaving section 316 m has total lane-changing rate of 812 lc/h. Shorter weaving distance may cause less lane-changing activity because drivers does not prefer to perform weaving at shorter weaving section as it is forced the drivers to perform weaving drastically in more crammed situation and risk to dealing with accident is huge. The findings shall help to understand more on causes of weaving turbulence at weaving section by referring HCM 2010 methodology.
