Analyst Drive allows users to run a dynamic estimation based off of inputs generated by a dynamic assignment performed by Cube Avenue. Analyst Drive will process the corresponding packet log file to generate the necessary route choice probability matrix used in the estimation based off of the individual packet contents of the file. These packets contain various information such as the route information with departure and arrival times, class identification and the assignment weight factor.

To perform a dynamic estimation the user needs to provide the program with the appropriate set of input files including Cube matrix files for each user class used in the assignment, the Avenue packet log file, and dynamic screenline or turning count files. Input matrices should contain a matrix tab for each time period in sequential order, and optionally may include a warm-up period OD matrix as the first tab in the matrix file (if using the WARMAT option). Note that Analyst Drive does not use confidence matrices in the estimation at this time, and so no confidence matrices should be present in any dynamic input matrix tabs. Currently, one dynamic screenlne file for each corresponding matrix file is required, but options similar to those available for static estimation for using fewer count sets than the number of user classes may be added in the future.

You may continue to:

• Using a warm start

• Estimating a single OD matrix from a multiple class problem

• Estimation with more time intervals than count sets

• Zero count screenline values
