Here is a link to an email I received from ITE about the future of their Trip Generation effort. Basically, they are looking at modernizing their Trip Generation system to include Urban Trip Generation and Person Trips. They’ve set up several committees to start to figure it out. Hopefully they develop a robust, filterable system like TRICS. A fundamental issue that needs to be addressed is how much modern, relevant data is included in their dataset.
I also love the idea of moving towards person trips to pin down trips made by all modes, but I’m unsure how to cost-effectively collect this data. I’ve posted several times on the ITE Community asking how others are collecting person trip data – with no response. I hope ITE will fund this type of data collection or promote government agencies/researchers collecting more of this data.
Here are 4 More Suggestions for ITE to consider:
- Tiered subscription pricing. Tiered subscription-based pricing so very occasional users can pay a reasonable fee to access the data while heavy users can pay a bigger annual fee that is actually cheaper for them per use. There are many cities out there that need to access this database once or twice a year. The days of making them buy a $412 book should be over.
- More frequent updates. Because traffic studies are based on this dataset, agency staff need the ability to go back and double check the calculations as part of their review. This probably means we can’t have a living dataset that is altered every time new data is submitted. However, there’s no reason a new edition can’t be published each January 1st.
- Access to previous Editions of Trip Generation. Whether the dataset is published on a ten-year cycle, a four-year cycle, or an annual cycle; we’ll end up with a traffic study submitted with data from one Edition that gets approved after the next Edition was released. Reviewers need to be able to access the most current dataset as well as the previous dataset. Researchers would also like the ability to access more than just the previous dataset.
- Provide incentives for professionals to upload trip generation data. I am happy to freely share our data at TripGeneration.org through a Creative Commons license, but I don’t see a reason to submit it through Transoft’s OTISS system who then profits from the data AND charges me back to access it.
I hope to get an opportunity to discuss the future of Trip Generation data at the ITE Annual meeting as advertised.
