In an era of declining infrastructure coupled with limited resources for transportation spending, local and state governments are turning to the ballot box to fund transportation measures. The ballot box can be an effective way to increase funding to create more livable communities through transportation. In 2016, with over $250 billion at stake, voters approved approximately 70% of measures. While it is easy to describe anecdotes to illustrate success stories of local ballot measures, tracking success across the country is challenging. The Center for Transportation Excellence (CFTE) has been tracking transit measures across the country since 2000. In 2016, the Eno Center for Transportation released a comprehensive Transportation Ballot Measures database covering all types of transportation across the country for the 2016 election. The Sustainable Cities Initiative at the University of Oregon recently built a comprehensive database of transportation ballot measures in California, Oregon and Washington covering 2005-2015. On Thursday, April 20 at 2 PM EDT/ 11 AM PDT, these organizations will team up for a webinar to discuss lessons learned from building databases to track transportation ballot measures and describe characteristics of successful measures.
