MICHIGAN STATEWIDE TRANSPORTATION MODELING SYSTEM. VOLUME X-A-1. AUTOMATED DESIRE LINE PLOTTING. STATEWIDE TRANSPORTATION PLANNING PROCEDURES

A typical transportation analysis technique used in the evaluation and display of transportation planning data is the desire line diagram. This type of diagram is used to display the distribution of travel on a particular segment of road. In the past, this has typically been a manual process because technology did not exist to simplify the operation. This report is the documentation of a process that will now allow the transportation planner to automate and therefore simplify the preparation and analysis of statewide travel characteristics. The process uses actual origin - destination trip tables from the statewide model. The actual desire line plot uses the trip data in the matrix to create a highway network plot that has only centroid links in it to represent the desire lines. /Author/
