and environmental factors. discussed in this chapter, and traffic and control factors discussed in uhaoter 31 l
The roadw n and envirnnmental factors that control the capacity of an approach are the physical I.n out ut the approach. in particular its width, the radii along w hich let'..

The e::pacin os an approach is measured indeper.dently of trattie and control factors and is expressed as the saturat<on flow.
Saturation flow is defined as the maximum flow. expressed as equnalent passenger

These satulation 110ws have to be amended for the etfeet of gradient. This moditica-;
tiui ha, been veported as a decrease or merease of 3 per cent in the saturation flow for evers 1 ;er cent of uphill or downlull eradient of the approash. ihe gradient ot the i
approuh was.fetined as the aserage slope between thg stop luie and a point on the approxh ni m betore it. At the sites where these obwrvation> were made, the slope connnued through the interseenon.
