Research Highlights

Instructional Modules for Obtaining Vehicle Dynamics Data with Smartphone Sensors

Roger Lindgren Charles (C.J.) Riley
Past NITC education grants to Oregon Tech provided funding for developing new graduate-level coursework in transportation (2014-15) and to support development of learning activities related to smartphone/ipod sensors for transportation structural health monitoring (2015-16). The request this year (2016-17) proposes to build on the success of these past two grants and support specific coursework development by the creation of learning activities (primarily field laboratory modules) related to… Read More

Improving Accuracy and Precision of Pedestrian Volume Estimates Using Advanced Machine Learning Approaches

Sirisha Kothuri Banafsheh Rekabdar
Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. Most agencies still use manual counting methods, however over the last decade, several automated technologies have been developed to count bicyclists and pedestrians. Due to cost and other resource considerations, permanent counts are still limited to small subsets of networks… Read More
