Bicycling is increasing in the United States -- the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (National Household Travel Survey, 2009). With the increase in bicycling rates, there is a critical need for cycling infrastructure, which includes on and off road bicycle lanes and paths, signs, markings, and signals. One of the key links in a bicycle network is signalized crossings of high volume and high speed roadways. At these intersect...

Transferability & Forecasting of the Pedestrian Index Environment (PIE) for Modeling Applications
Kelly Clifton
There have been important advances in non-motorized planning tools in recent years, including the development of the MoPeD pedestrian demand model (Clifton et al., 2013, 2015). This tool and others are increasingly requested by governments and agencies seeking to increase walking activity and create more walkable places. To date, the MoPeD tool has been piloted with success in the Portland region using data unique to Metro, the metropolitan planning organization. However, there is increasing ...
