In the past, much, or all, of recurring congestion was felt to be a systemic problem ("not enough lanes") but much of the root cause of recurring congestion is in fact subordinate locations within a facility; i.e.,"bottlenecks" and chokepoints. Elsewhere on the same facility and during the same hours, the facilityruns free. This document is meant to discuss when, where and how to study small, localized sectionsof a facility (e.g., on/off ramps, merges, lane drops, intersections, weaves, etc.) In cost-effective means.Some chokepoints are (or seem) obvious in their solution; add a turn lane, widen a stretch of highway,retime a signal, or separate a movement by ramp. However, the solution can often lead to hidden orsupplementary problems; hidden bottlenecks, disruptions upstream, or undue influence on abuttingaccesses, etc Analyzing localized sections of highway is different from analyzing entire corridors orregions. Micro simulation analysis products vary in their target applications and purported results.This document will provide guidance that specifies the choice of analysis tools and inputs necessary toanalyze localized problem areas. It also provides some guidance as to when analysis it warranted, andwhat data inputs are required.
