Abstract

Describe how the capacity of merging links to high speed roads may be estimated. A single lane link merges with a two lane highway and the merging relationship between entering link flow and upstream main carriageway flow is

$${\rm{Link entry flow = 1600 - 0}}{\rm{.44 upstream flow}}$$

Develop a diagram illustrating the variation of link entry capacity with mainline flow.
