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
