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

3
AAP

• Provides easy access to PASSER II and TRANSYT 7F
• Using one data input scheme

4
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

5

• Bandwidth efficiency
• Ratio of thru bandwidth (in both directions)
  divided by twice the cycle length

6
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

7
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
• Time Space Diagrams

Artery Data

• Speeds are automatically entered as the values
  input in Artery setup
• They can be changed individually, if desired

15

• Mode can be
• P- pretimed control
• F - actuated control
• S- semi-actuated control
• artery is assumed to be the non-actuated phase
• I no signal control

If the lengths in the reverse direction are the
same as the forward, press F9 and the lengths
will be automatically input

Artery Data

• Traffic Volume
• Lanegae
• Right turns are assumed to be shared
• Only enter the number of lanes under the the
  right turns if there is an exclusive right turn
  lane
• Peak Hour Factor
• Saturation Flow
• Minimum Green Times
• Speed
