Version 2.2 Documentation• What’s included:
1. Overview of features & description (Ch. 1)
2. Inputs & model specification (Ch. 2-8)
3. Validation (Ch. 9)
4. User’s application guide (Ch. 10-21)
5. Technical appendix• Detailed model output summaries• Application listings (scripts, batch files, etc.)• Flowcharts
3/21/08 Ver2.2 Presentation to the TFS 5
Distinguishing Features of Ver. 2.21. Commercial vehicle model added
2. Revised/moderated external traffic forecasts
3. Revised volume-delay functions and added queuing delay function to freeway volume-delay formulation
4. Reduction/removal of model adjustments (K factors, etc.)
5. 60 Iterations of user equilibrium traffic assignment
3/21/08 Ver2.2 Presentation to the TFS 6
Latest Refinements: #1 of 3Modified approach for disabling ‘dummy links’ from queuing delay
• Revised approach identifies link disabling on a time-of-day basis; this is more accurate
3/21/08 Ver2.2 Presentation to the TFS 7
Latest Refinements: #2 of 3Modified highway toll skims development wrt. the mode choice model
• Highway skims are normally developed by mode (SOV, HOV 2-occ, HOV 3+occ) and include time, distance, toll
• Tolls are now expressed differently, based on toll policy type:– Fixed toll facilities (e.g., Gov. Nice Bridge,
Dulles Toll Road)– Variably priced toll facilities (HOT Lanes in
Virginia, electronic toll lanes in Md.)

Special Modeling Applications(Reference page 1-10 in Model Report)
• Some forecasts are developed using elements of two model executions. This approach is used to reflect special policy conditions:
1. Transit constraint: 2010 transit trips are used to constrain modeled 2020, 2030 transit trips to/through the regional ‘core’
2. HOT lane modeling: HOV level-of-service matrices are specially developed in ‘initial’ model executions; the ‘initial’ HOV skims are used in the ‘final’ model execution
3/21/08 Ver2.2 Presentation to the TFS 16
Transit Constraint (Applied in 2020, 2030 simulations)
– Reason: Infrastructure limitations will constrain peak Metrorail travel to/through the regional ‘core’ to 2010 levels
– Approach: 1. 2010 model run is executed; 2010 final iteration
transit trips created 2. 2020/ 2030 model runs are executed; after mode
choice step, peak transit trips to/through the regional core are compared to 2010 levels.
3. 2020/2030 peak transit trips exceeding 2010 levels are converted to auto trips
3/21/08 Ver2.2 Presentation to the TFS 17
HOT Lane Modeling (Applied in 2010, 2020, 2030 simulations)
• Reason: VA policy assumes that HOV service levels will be maintained with HOT lane operation
• Approach:1. An initial run is executed with the HOT lane facility simulated
as an HOV-priority facility (hypothetical). HOV level of service (LOS) matrices for each iteration are developed. This is known as a ‘BASE’ model execution
2. A second model run is executed, with the HOT lane facility accordingly coded (pay SOV’s and free HOV’s are allowed access). Initial tolls rates are used. The final assignment is then run iteratively, so that tolls rates are developed by segment and time-period (off-line step)
3. A final run utilizes the HOV LOS matrices developed in Step 1 with the toll rates developed in Step 2. This final model execution is known as the ‘Conformity’ run
3/21/08 Ver2.2 Presentation to the TFS 18
TPB Forecasts Must Be Executed in Sequence
• Model years available: 2000, 2002, 2005, 2008-2010, 2020, 2030
• ‘Early’ years (2000 – 2009) are not dependent upon prior runs
• ‘Out’ years 2010-2030 are dependent on prior runs; recommended sequence:
1. 2010 Base 2. 2010 Conformity3. 2020 Base4. 2020 Conformity5. 2030 Base6. 2030 Conformity
3/21/08 Ver2.2 Presentation to the TFS 19
Version 2.2 Model Execution
• Applied in a ‘command prompt’ window
• Structured application – Standardized subdirectory system– Pre-established batch files– Generically named inputs and outputs that are
established in specific subdirectories
3/21/08 Ver2.2 Presentation to the TFS 20
Why use specific subdirectories, generic names, and batch files?
• It minimizes model preparation time • Generically named inputs and outputs
facilitates the ability to prepare comparative summaries between alternatives
• It enables the analyst to focus on what’s important: – the accuracy of inputs– the analysis of outputs

Batch File Types in the Root SD
NOTE: the _Year_ variable must be accurately defined (e.g. ‘_year = 2030’)
Batch Files Purpose
Primary batch file(e.g., Runall2000.bat)
Defines secondary batch file, output subdirectory (used in sec. batch file, and generates run time / log files
Secondary batch file (e.g., Runall_2000.bat)
Defines sequence of iterations and modeling steps, defines year (_year_), and model description (_Alt_)
Model Step batch files (Set_Factors.bat) . . . (Highway_skims.bat)
Calls scripts/ programs to execute individual modeling steps and to provide iteration-specific file output names
User enters this batch file name at command prompt
Pre-established file ‘called’ by primary batch file

Notes: 1. Limit Codes are 0,1 = General Use, 2 = HOV2,3+ only, 3 = HOV 3+ Only, 4 = Truck Prohibited, 5 = Non-Airport
Vehicles Prohibited, 6-8 = (unused), 9 = ‘Transit Only’ link (links used to more accurately depict coded transit routes, but are below the grain of the zone system; these links are not included in the highway assignment process).

Conclusions• Version 2.2 model is now ‘on-line’• TPB is currently responding to 10 requests• Version 2.2 represents an improvement in the
TPB’s travel forecasting practice– Fewer adjustment factors used– Freeway queuing delay is now addressed– More realistic external traffic assumptions used
• Version 2.2 will continue to be monitored and refined, as is the case with any production model
• TPB’s models development activities are continuing: Version 2.3 is in progress
