T.P.D.M.V.2.2 (Al/2001) 2.3 Passenger Car Units 2.3.1 P.C.U. Values 2.3.1.1 Passenger Car Unit values are given in Table 2.3.1.1. Although p.c.u.'s are no longer used in the determination of the capacities of roundabouts or links these values have been included for reference purposes. Private Car, Taxi Table 2.3.1.1 - Passenger Car Units Urban Standard 1.0 Eauivalent Value in P.C.U.'s Rural Standard 1.0 Roundabout 1.0 Traffic Signal Design 1.0 Light Goods Vehicle 1.5 1.5 1.5 1.5 Motor Cycle Motor Scooter 0.75 1.0 0.75 0.40 Medium Goods Vehicle Heavy Goods Vehicle Terrain Ave Hilly Ave Hilly 2.0 3.0 2.0 4.0 2.5 3.0 2.5 3.0 2.8 1.75 2.8 1.75 Bus 3.0 4.0 3.0 4.0 2.8 2.0 Pedal Cycle 0.35 0.5 0.5 0.2 Tram 3.0 - - 3.5-5.0+ Light Bus 1.5 1.5 1.5 1.5 Special purpose bus 2.0 2.0 Light Van 1.25 1.25 1.25 1.25 Tractor unit 3.0 3.0 2.3.1.2 For Medium or Heavy Goods Vehicle pcu values for hilly conditions are appropriate where the gradient is greater than 4%, or there are long lengths of 4% gradient. 2.3.1.3 For trams pcu values vary from 3.5 pcu's for a clear approach to a junction, to 5.0 pcu's where a tram island is sited near an approach. Where a tramway reserve is provided or where the frequency of tram movements is so high as preclude the use of its lane by other vehicles, that lane should be excluded in capacity calculation for mixed traffic. 2.3.1.4 Where, in any context, it is considered that p.c.u.'s are appropriate for design or other purposes, the values used must be in accordance with Table 2.3.1.1.
T.P.D.M.V.2.2 (Al/2001) 2.4 Design Flow Characteristics 2.4.1 Design Flow 2.4.1.1 Design flow is the maximum volume of vehicles using the road without the traffic density becoming such as to cause unreasonable delay, hazard or restriction to the drivers freedom to manoeuvre. Typical values are shown in Table 2.4.1.1 Table 2.4.1.1 Design Flows for Two Way Urban Roads 2 lane carriageway Undivided carriageway Dual carriageway Peak hourly flow Veil/hour, both directions of flow * Peak hourly flow Veh/hour, one direction of flow Peak hourly flow Veh/hour, one direction of flow i Road Type 4 lane Dual 2 lane Dual 3 lane j 6.75m 7.3m 10.0m 123m 13.5m 14.6m Dual 6.75m Dual 7.3m Dual ! ll.Omi Expressway/trunk road 3600 5700 Primary distributor no frontage crossings, no standing vehicles, negligible cross traffic District distributor frontage development, side roads, pedestrian crossings, bus stops, loading restrictions at peak hours. 1400 2000 1700 3000 2500 2550 2800 i 1700 1900 3050 2100 *2950 *3200 *4SOO j 1 "" 60/40 directional split can be assumed. * Includes division by line of refuges as well as central reservations; effective carriageway width excluding refuge width is used 2.4.1.2 The design flows in Table 2.4.1.1 allow for a proportion of heavy vehicles equal to 15%. No allowance will need to be made for lower proportions of heavy vehicles; the peak hourly flow at the year under consideration should be reduced following Table 2.4.1.2 when the expected proportion exceeds 15%:
