Psychology teaches us that implicit biases—attitudes we hold on a level below consciousness, and may not even be aware of—can have a heavy influence on split-second decisions.

In a fast-paced activity like driving, with a lot of moving parts in a complex environment, we make those snap decisions all the time. There are obvious safety implications to this, particularly for the most vulnerable road users. That’s why TREC researchers are becoming more and more interested in studying implicit bias and social psychology as it relates to transportation behavior.

The latest report from the NITC program, Exploring Drivers’ Attitudes and Behaviors toward Bicyclists: The Effect of Explicit and Implicit Attitudes on Self-Reported Safety Behaviors, is a dissertation by NITC fellow Tara Goddard.

With a focus on driver-cyclist interactions, Goddard dives into the social psychology of roadway interactions and comes up with some interesting takeaways for practitioners and researchers. Before moving to Portland in 2011 to begin her Ph.D., Goddard was the bicycle/pedestrian coordinator for the City of Davis, California, and says that it’s important to understand the mechanisms at...

Light detection and ranging (LIDAR) technology is reshaping the civil engineering profession and offers many unique advantages. National efforts such as the 3D Elevation Plan (3DEP) are helping increase the availability of LIDAR data. LIDAR is one of the crucial technologies that is transitioning the world of civil and construction engineering from 2D paper-based design to 3D digital design. The high spatial resolution and accuracy capabilities of LIDAR have led to increased efficiencies, improved analyses, and more informed decision making.

A further advantage of this dataset is that multiple people can use the same dataset for a variety of purposes across multiple disciplines. The visual nature of the dataset also is more intuitive than traditional data acquisition and analysis techniques. This presentation will provide a brief background of LIDAR , its capabilities, limitations and platforms, and discuss its current and future role in civil engineering. Examples of a wide range of transportation, geotechnical, coastal, and structural engineering, science, and planning applications will be presented including development of mobile LIDAR guidelines for...
