Staged Crossings at Sign-Controlled Intersections

Modified on: 2018-05-05 07:23:52 +1000

SIDRA INTERSECTION network analysis technique can be used to model a large number of traffic facilities that involve closely-spaced intersections and interchanges including alternative intersections and interchanges. This includes modelling Staged Crossings at Sign Controlled Intersections.

The Staged Crossing model as a network can be used (i) when there is storage available in the central (median) area that allows the turning movement to slow down or stop and give-way / yield to the main road Through traffic stream and (ii) when there is an acceleration lane for merging.

Detailed information on modelling Staged Crossings at Sign-Controlled Intersections can be found in SIDRA INTERSECTION User Guide, Section 5.10.7.  

Example project files are available for download using the following links.

Staged Crossing - Standard Left
Staged Crossing - Standard Right
Staged Crossing - US HCM (Customary)

The use of old version project files which used a diagonal leg as a trick to model these crossings is not recommended and support is not available for this old method of modelling these facilities.
