Two-moo two-way roads
By definition these roads have one lane for use by trafiic in each direction, and overtaking of slower vehicles requires the use of the opposing lane when sight distance and gaps in the opposing traffic stream permit. Two-lane roads compose the great majority of most national road systems.Two-lane roads perform a variety of traffic functions. For example, efficient mobility is the main function of major two-lane roads that are used to link large traffic generators or as inter-city routes; thus consistent high-speed operations and infrequent overtaking delays are normally desired for these roads. High-volume two-lane roads are sometimes used as connectors between two major dual carriageway roads, and motorist expectations in relation to quality of service are also usually high for these roads. In the case of two-lane roads in scemc and recreational areas, a safe roadway is required but high-speed operation is not expected or desired. Two-lane roads in rural areas need to provide all-weather accessibility, often for fairly low traffic volumes; in these locales cost-effective safe access is the dominant policy consideration and high speed is of lesser importance.
When vehicles are operating under level of service A conditions on two-lane two-way roads, motorists are able to drive at their desired speed, overtaking demand is well below passing capacity, and almost no platoons of three or more vehicles are observed. Level of service B characterises the region of traffic flow where the overtaking demand needed to maintain desired speeds becomes significant. As volumes increase and approach the lower boundary oflevel B the overtaking demand approximately equals the passing capacity, and the number of platoons forming in the traffic stream begins to increase dramatically.
Traffic volumes are so high at level of service C that significant reductions in overtaking capacity occur and these are associated with noticeable increases in platoon formation and platoon size. Although traffic flow is still stable, it is more susceptible to congestion caused by turning traffic and slow-moving vehicles.
Unstable traffic flow is approached within level of service D and, at high volumes, the opposing traffic streams essentially begin to operate separately. Overtaking demand is very high while passing capacity approaches zero. Average platoon sizes of 5-10 vehicles are common. The proportion of no-passing zones usually has little influence on overtaking. Turning vehicles and/or roadside distractions are causes of major shockwaves in the traffic stream.
