Survey and Economic Analysis of Pavement Impacts from Studded Tire Use in Alaska.

ITE

Ph.D. Candidate, Mahmoud Arafat presented his research work that was done as part of his master degree at the University of Alaska Anchorage. Mahmoud developed a methodology to analyze the impact of using studded tires on pavement rutting and damage in cold regions. His report is published on the TRID database.

"Achieving Vision Zero: Applying Lessons from Organizational Systems to Transportation Systems Planning and Design" by Dr. Eric Dumbaugh, Associate Professor, Florida Atlantic University.

ITE

Dr. Dumbaugh focused on achieving Vision Zero in his lecture. He took a different approach in addressing traffic crashes. His strategy is applying lessons from organizational systems to transportation systems planning and design. Dr. Dumbaugh believes we can reduce crashes by addressing on human behavior.

"Resilience Measure for Infrastructure Restoration Plan Optimization Considering Unmet Demand in Transportation System after Disruptive Events" by Dr. Tingting Zhao, Postdoctoral Researcher, CEE, USF.

ITE

Dr. Zhao provided an overview of natural and human-caused events that may cause disruptions. She talked about critical infrastructure resilience, its ability to resist, and adapt to disruptions and return to normal functionality.

"Proactive Planning for Catastrophic Events in Supply Chains" by Dr. Evangelos Kaisar, Professor & Director, Freight Mobility Research Institute, FAU.

ITE

Dr. Kaisar emphasized that transportation infrastructures are increasingly vulnerable to catastrophic events such as hurricanes or manmade attacks. Therefore, proactively planning for these types of events should be a priority for transportation official and supply chain managers.

"Investigation of Heterogeneity in Severity Analysis and Examining Potential Sources of Heterogeneity in Large Truck Crashes"

ITE

This topic was presented by Ghazaleh Azimi, a Ph.D. candidate at the Department of Civil and Environmental Engineering in Florida international University. In her study, she developed a random parameter model that was divided into driver, vehicle, and roadway characteristics to investigate heterogeneity in severity analysis and identify the potential sources of heterogeneity in trucks. The study used data set from 2007-2016 with a focus on vehicle-in-motion crashes with different severities. A random parameter ordered logit model was developed to find the sources of heterogeneity. The results from the model showed that factors with a positive impact on Heterogeneity in Large Truck Crashes were gender, age, speed, vehicle type and vehicle model".

Transit Modeling using STOPS

ITE

This topic was presented by Mr. Ashutosh Kumar, a Senior Project Manager at Connetics Transportation Group. Transit Modeling using the STOPS software was presented and discussed during the event. The presentation defined STOPS as the simplified Tips on Project Software. Also, the topic highlighted the overview of Transit Modeling, overview of STOPS. Transit Modeling is the representation of the transit supply and travel behavior, it consists of many elements and steps including route coding. The presentation described the different types of transit model and showed the FTA capital investment grand program that provides funding for fixed guideway investments. STOPS requirements are friendly regarding software, and hardware. In addition, it is easy to understand and easy to implement.

"Modelling Travel Behavior, Spatial Analysis, and New Synergies" by Dr. Ing. Lissy La Paix from the University of Twente.

ITE

Dr. La Paix introduced integrated innovative engineering approaches. In her lecture, she covered topics on ITS, traffic safety, modelling travel behavior, transit oriented development, evaluation of Dutch cycling patterns, etc.
