PASSER II SOFTWARE
PASSER II
Progression Analysis and Signal System Evaluation Routine
Traffic Signal Optimization model Texas Transportation Institute (TTI)
Widely used model for arterial routes Component program of AAP
Arterial Analysis Package Pre-Processor
AAP
Provides easy access to PASSER II and TRANSYT 7F Using one data input scheme
PASSER II
A macroscopic, deterministic optimization model designed to develop “maximal bandwidth” timing plans on an arterial highway
Objective function of maximizing bandwidth efficiency Ensures good perceived progression
timing plans
Bandwidth efficiency Ratio of thru bandwidth (in both
directions) divided by twice the cycle length
Inputs
Traffic volumes, laneage Saturation flow rates Minimum phase times Permitted phase sequences Analysis methods
To evaluate existing conditions• Enter offsets and splits
To optimize • No information is entered
Outputs Three basic types
Input data report• Gives all input data in a structured format
Design recommendations• Including phase sequences, cycle length, offsets and splits • measures of effectiveness (MOE) values for
• Bandwidth efficiency• Bandwidth ‘attainability’• Degree of saturation• Delay• Probability of queue clearance and fuel consumption

Artery Data
Speeds are automatically entered as the values input in Artery setup
They can be changed individually, if desired
Mode can be P- pretimed control F - actuated control S- semi-actuated control
• artery is assumed to be the non-actuated phase
