The roll-out of HCM 2010 caused us to look at the different software packages out there for doing capacity analyses and traffic forecasting. We settled on PTV's Traffix/Vissim bundle. We are very happy with our switch. I believe we are doing better analysis by using these flexible software tools (vs. our old spredsheet/Synchro/SimTraffic methods) and we are working more efficiently.
Karen Giese from PTV America has been keeping us in the loop on their development of Vistro, which is a completely new software package that will replace Traffix. I couldn't be more excited. Vistro will be the complete traffic analysis software the industry is currently missing. Here are some of the key features -
- Faithful implementation of HCM 2010 and a half dozen other methodologies for capacity analyses. Including traffic control warrant analyses.
- Powerful traffic signal timing optimization.
- Very easy to use graphical interface.
- Seamless export to Vissim for micro-simulations for precise queue and spillback analyses.
- Simple scenario manager to manage multiple build-out scenarios, development phasing, alternate mitigation testing.
- Fastest path (or user defined) distribution of development traffic to the edge of the study network.
- And the most exciting for preparing studies – complete export of tables, figures and summary reports. This will make report assembly (and revisions) amazingly efficient.
This is going to be the complete package for doing comprehensive planning, traffic impact studies, corridor studies, and traffic signal optimization. It will also be the middle ground between PTV's Visum macro-scopic modeling software and their Vissim micro-scopic modeling software. The seamless integration should be very powerful.
These details are from a webinar Karen gave us last week (sorry – I promised not to share the slides). PTV is launching Vistro at the annual ITE meeting in August and will ship the software to customers this Fall. There will be a soft launch at the PTV user meeting this week in Minneapolis. Karen promised to give me screenshots and more details at the user meeting. I'll post Part 2 of this blog with more details in a couple of days.
