1 TEXPACK Integrated Travel Demand Modeling Application Texas Planning Conference June 2016

2 Presentation Overview What is it and what is different? Why do this? What does it look like? Where are we now? Where are we going with this? 2

3 What is TexPACK? Texas Package Suite of Travel Demand Modeling Software Trip generation and distribution techniques Integrated into TransCAD travel demand modeling platform Takes advantage of inherent GIS capabilities 3

4 What is TexPACK? No longer need to invoke sequential models one step-at-a-time Although an end-user certainly still has that option Automates a number of steps Application/model familiarity Hopefully minimizes potential for errors Reporting and mapping mechanisms 4

5 What is TexPACK? Continues with initiative to standardize: Folder structures File naming conventions Attribute/data naming conventions Model architecture Common platform for interpreting results statewide 5

6 Why Implement TexPACK? 1. Increase use of demand model applications by improving application interface, 2. Create a standard platform to create, apply and deploy models throughout the state, 3. Create a common system for measuring and communicating results, and 4. Create a system that permits flexibility for enhancement 6

7 TexPACK: What Does It Look Like? Scenario Manager Apply single stage Apply all stage Stage settings Stages Version information 7

13 TexPACK: What Does It Look Like? Toll/Generalized Cost 13

14 TexPACK: What Does It Look Like? Reporting Feature 14

15 TexPACK: What Does It Look Like? 15

16 TexPACK: What Does it Look Like? Mapping Feature 16

17 TexPACK: What Does It Look Like? 17

18 TexPACK: What Does It Look Like? Folder structure All folders stored in C:\TxDOT\study area TxDOT requirement 18

19 TexPACK: What Does It Look Like? Attribute/data conventions TxDOT requirement 19

20 What Has Been Converted? Base and Forecast Base and Forecast Base and Forecast Base and Forecast Base and Forecast Base and Forecast 20

21 What Has Been Converted? Forecast Only Base Only 21

22 What Has Been Converted? Base and Forecast With Interim Years Base and Forecast With Interim 22

23 What Has Been Converted? Under Development Pending Conversion Under Development 23

24 What Has Been Converted? Alternative System Alternative System 24

25 Deployment Pending? Needs to be scheduled Needs to be scheduled 25

26 Where are we going? Version 1.1 Has been or will be delivered Version 1.2 ish Laredo travel models Generalized cost (account for tolls) Multi-class assignment Truck Auto Utilizes bi-conjugate assignment technique Delivered to MPO 26

27 Where are we going? Bi-Conjugate 1.210E E E-04 Relative Gap 6.100E-04 FW BFW 4.100E-04 Did not converge 2.100E E Number of Iterations 27

28 Where are we going? Version 1.2 ish Lower Rio Grande Valley 2009 Base Year with 2040 pending Forecast Application Integer 100 th s trip matrices (previously delivered) X100 format Generalized cost MMA assignment technique Truck and auto-only toll lane capability Bi-conjugate assignment technique Time-of-day (TOD) models This functionality has not been delivered to Valley MPOs yet 28

29 Where are we going? Version 2.0 (pending) Envisioned as new approach to modeling in Texas Time-of-day models No longer daily models 29

30 Where are we going? Version 2.0 (pending) Generalized-cost MMA Truck and Auto trip tables Capability to address truck and auto-only toll facilities Facility types for HOV, HOT, and toll lanes Capability to study alternative demographic scenarios for same year 30

31 Where are we going? Version 2.0 (pending) Utilize TxDOT purchased INRIX speed/travel time data Iterative feedback resolution No longer integer trip matrices Additional reporting mechanism(s) 31

32 Where are we going? Other enhancements under consideration Generation of person trips rather than direct generation of auto trips Auto-occupancy models Preservation of trips by income category Stronger accounting of truck/freight flows Mode choice 32

33 Where are we going? TexPack has been tested in Version 7.0 Results delivered to TxDOT-TPP Examining flow-chart options So what is this? 33

34 Where are we going? 34

35 Where are we going? Team Management of the TDM Development and Application Process 35
