Trouble free traffic flow is always dependent on the limits of capacity of the road networks, particularly where large traffic volumes arise or where unexpected disturbances occur on inter-regional roads. Capacity is defined as the highest possible traffic loading, i.e. The traffic volume per hour which a traffic lane will take under actual traffic and carriageway conditions. The author presents capacities for various road types (two-way streets, residential and service roads, motorways) and the most favourable capacity speeds, i.e. The speed values at which the highest possible capacities can be guaranteed. Junctions, t-junctions, and crossroads determine the capacity of a stretch of road, and this may be improved by traffic signals. Special events (demonstrations, performances, construction sites, accidents), result in a reduction in the capacity. The author presents some reflections on traffic capacities. He closes with a list of measures for the improvement of capacity. /TRRL/
