Presentation Transcript

1. More on Modeling / Tools What do we have now? Where do things go wrong? How can I match the right tool?

2. If you give people tools, and they use their natural abilities and their curiosity, they will develop things in ways that will surprise you very much beyond what you might have expected. Bill Gates

3. What Do We Have Now? Division of Planning sent survey to multiple consultants with variety of software experience Multiple analysis types and software tools listed Rankings B - Best (if you have time and money) G - Good fit O - Ok if it has be quick & cheap U Use is not recommended NE No Experience

4. What Do We Have Now? Tools Included in Survey: Transyt-7f Highway Capacity Software Vistro Synchro Microsimulation Travel Demand Models VISSIM TransCAD TransModeler VISUM CORSIM / TSIS Cube Sketchplan / Spreadsheets

5. What Do We Have Now? Analyses Included in Survey: Signal Timing / Coordination Turning Movement Analysis Weave Analysis Intersection or interchanges alternatives Queue, LOS, and Delay Analysis Tolling, HOV, Congestion Pricing, etc Alternative Routes or Diversion Volumes

6. What Do We Have Now? Survey Results

7. What Do We Have Now? Survey Results No one tool does it all Microsimulation requires help to do signal timing / coordination In some instances, HCS can do a lot of the work as a microsimulation Macro level models are fine for diversion, new routes, and possible tolling CORSIM is an honest microsimulation tool Sketchplans / Spreadsheets are quick and cheap but give general answers Vistro is highly rated, but not widely used

8. What Do We Have Now? Even with a panel of experts , there is some difference of opinion This can lead to: Correct applications Wrong applications Gray areas Limitations Cost and Time extensions

9. Where Do Things Go Wrong?

10. Where Do Things Go Wrong? Early Communication Communication failures are common (at all levels) Have discussions early (pre-scoping) to identify what they are (Hint: it may not include modeling) Include Design, Planning and / or Traffic Engineering staff depending on the intended application May require one or more depending on length of project May require both Central Office and District Staff

11. Where Do Things Go Wrong? Communication Scoping At the scoping meeting, discuss what is needed for this project (and beyond) don t short-change the project When modeling is on the table, invite the subject matter experts Be sure to discuss: Schedule Expected Effort Desired Outcomes (short term / long term) Data needs to meet goals If necessary, have a follow-up scoping meeting / call solely on traffic forecasting / modeling / analysis

12. How Can I Match the Right Tool? The toolbox is wide open: How do you decide? How much budget is available? Don t waste it but don t shortchange it. Is the schedule tight? Proper data collection can take a while. Some models can take months to build. Does one size fit all? Can you overthink it?

13. How Can I Match the Right Tool? Quick Examples: I-265 Programming Study Macro data for a micro analysis Multiple tools Different expectations I-65 to Hodgenville Planning Study Initial traffic forecast requested before scoping meeting with consultant Study area scenarios changes at scoping meeting no updates made to request
