• Project: Performance Monitoring for Safe and Livable Communities: Fusing Data to Improve Arterial Operations for All Users • PI: Michael Dixon (UI) • Co-Investigators: Ahmed Abdel-Rahim (UI), Mike Lowry (UI), D. Kim (OSU), J.D. Porter (OSU); Yinhai Wang (UW) Safe travel and livable communities require data that can characterize all modes, not just motorized vehicles. The problem many transportation professionals face is measuring performance and correcting poor performance to meet community goals. Quality performance measurement requires strong data support. Although the deployment of Intelligent Transportation Systems (ITS) technologies has increased data availability, they are mostly for auto vehicle traffic. The availability of pedestrian and bicycle data is still poor in most areas. Also, the available auto traffic data streams are typically stored separately without effective mechanisms for integration. To fill up the gap, this project will develop a new pedestrian and bicycle data collection technology to address the data needs for active transportation and integrate data from multiple sources for a more complete understanding of how to improve arterial traffic safety and how arterial systems serve each mode and steps that professionals should take to improve service. The data to be integrated will include wireless device ID, video, high resolution traffic controller data, and weather information. The project will leverage the strengths of these data sets to meet information and security demands for more effective infrastructure monitoring, performance management, and performance measurement for safer and more livable communities. • Project: A Platform for Proactive Risk-Based Slope Asset Management • PI: Andrew T. Metzger (UAF) • Co-Investigators: Pedro Arduino (UW), Michael Olsen (OSU), Armin Stuedlein (OSU), Joseph Wartman (UW) Unstable slopes, including landslides, rock falls, and debris flows, present significant risk to safety and regional commerce and represent a chronic concern for highway mangers. Due to the widespread spatial and temporal distribution of these problems, most states have, or are taking, measures to manage slopes along their highway alignments. However, given the physical nature of slopes along highway corridors, they pose a number of challenges when deciding where to allocate funds as well as from an overall asset management perspective. This is compounded by the level of effort currently required to survey, inspect and characterize slopes for the purpose of condition assessment. Slope assessment has traditionally been laborious and costly, but altogether necessary due to the potential consequences of a failure. Current best-practices for management do not necessarily facilitate proactive slope management — identifying and remediating hazardous conditions before a failure occurs. The objective of this project is to develop a platform that will facilitate an objective programming of DOT resources for rock-slope assets within highway corridors. This platform should take the form of an administrative tool that will enable highway owners to make informed decisions on how best to program resources related to rock-slope inspection and remediation. The platform will be risk-based. That is, implementation of the products of this project will help qualify/ quantify the level a risk a rock-slope poses to the highway corridor customers (users) based on the current condition and importance metrics of the corridor. - 8 Pacific Northwest Transportation Consortium
