| Summary: | This research is aimed at studying factors that influence saturation flow at signalized
intersections in Kelang Valley. In this study local drivers and vehicles characteristics,
geometric design and traffic regulations are taken into considerations. The results
show that the relationship introduced by Webster and Cohbe, gives an underestimated
value of saturation flow at any given approach. Comparison between three
most frequently used models i.e. Webster and Cohhe, Akcelik and Ellson and Kimber
shows that Kimber model gives a more realistic estimation of the effects of turning
radius magnitude and percentage of turning vehicles on the local saturation flow.
Passenger-car unit values recommended by Webster and Cohbe give a close
estimation to real conditions for all types of vehicles except for buses |
