Accurately modeling the realistic and unstable traffic dynamics of human-driven traffic flow is crucial to being able to understand how traffic dynamics evolve, and how new agents such as autonomous vehicles might influence traffic flow stability. This work is motivated by a recent dataset that allows us to calibrate accurate models, specifically in conditions...

A research investigation was conducted on the erosion potential of stabilized subbases under concrete pavements and asphalt layers supporting concrete overlays. Through field surveys and testing in Illinois, this project evaluated if existing concrete pavements with stabilized subbases and concrete overlays were exhibiting potential erosion of the underlying...

This report explores the issues public authorities must address when establishing data-reporting mandates and policies. Transport systems and the people using them generate an ever-increasing amount of data which can help improve transport system performance. The risks from missing or overly broad reporting policies can be mitigated by following reporting...

This report documents a project to develop a new laboratory fatigue relationship to predict the performance of foamed bitumen stabilised (FBS) materials. The project focused on extensive laboratory experiments including indirect tensile testing and flexural testing to determine the modulus, strength, and fatigue characteristics of FBS samples prepared and...

This report develops and verifies material and structural models for asphalt mixture performance-related specifications (AM-PRS). The models the research team developed and verified in this study include the simplified viscoelastic continuum damage (S-VECD) model for fatigue cracking, the shift model as a permanent deformation model, the healing model based on...

Limited transport options in rural and remote areas hinder access to basic services, jobs and social activities. This report presents international best practices and recommendations for transport provision in communities where conventional public transport is difficult to sustain. It examines how sustainable accessibility for people without access to a car...

During the winter season, snowmobile riders in many jurisdictions use trails that are usually managed and maintained by snowmobile clubs and associations. The problem lies when these trails intersect with vehicular highways or paved park trails owned and maintained by a public agency. A single crossing can see thousands of snowmobiles in a single season, which...
