Exploring Data Fusion Techniques to Estimate Network-Wide Bicycle Volumes
Sirisha Kothuri Joe Broach , Nathan McNeil , Kate Hyun , Stephen Mattingly
In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where.
Traditional bicycle counters can provide data for limited sections of the bike network, often these counters are installed at important locations like trails or bridges. While limited in location, they count everyone who bikes by. Meanwhile, GPS & mobile data cover the entire transportation network, but that data only…

Effectiveness of Transportation Funding Mechanisms for Achieving National, State and Metropolitan Economic, Health and Other Livability Goals
Rob Zako Rebecca Lewis
The Moving Ahead for Progress in the 21st Century Act (MAP-21), adopted in 2012, established national performance goals for Federal-aid highways in seven areas. (Federal Highway Administration, n.d.) MAP-21 requires states and metropolitan planning organizations (MPOs) to establish performance-based planning processes, set targets (performance measures), and link planning and funding to these targets.
States and MPOs have different mechanisms for allocating funding from various sources to…
