To provide information for this model, ITS has studied certain characteristics of straight pipe sections of freeway (away from the influence of ramps) for two, three and four lane sites as described in this paper. These characteristics include lane distribution vs. flow, lane changing vs. flow, and speed vs. flow data for three different sites. One site has a wealth of data points near capacity and the occupancy, mean flow and standard deviation for this data has been determined. Additionally, this research further demonstrates the difference between the value of capacity of a freeway lane cited in the Highway Capacity Manual (HCM) and actual values at these sites, and compares the speed flow curves developed at these sites to the 1985 HCM curve and the JHK curve.Read More
