Multilane Highways: Multilane highways are similar to freeways in most aspects, except for a few key differences: - Vehicles may enter or leave the roadway at at-grade intersections and driveways (multilane highways do not have full access control). - Multilane highways may or may not be divided (by a barrier or median separating opposing directions of flow), whereas freeways are always divided. - Traffic signals may be present. - Design standards (such as design speeds) are sometimes lower than those for freeways. - The visual setting and development along multilane highways is usually more distracting to drivers than in the freeway case. Determining Level of Service (LOS): 1) calculate Free Flow Speed (FFS); 2) calculate Analysis Flow Rate ( Vp ); 3) calculate density ( D ); 4) determine LOS using Table 6.11 or Figure 6.4. FFS = BFFS - f LW - f LC - f M - f A Eq. 6.7 Where, FFS = estimated free-flow speed (mean speed of passenger cars operating in flow rates up to 1400 pcphpl), in mph
