The availability of connected vehicle (CV) data, even at lower market penetrations, can be sufficient to support critical transportation performance measurement and management functions. This webinar will discuss the use of CV data to estimate metrics that can be currently estimated using existing data sources including those related to mobility, reliability, and environmental impacts. In addition, the webinar will discuss the estimation and utilization of additional mobility and safety metrics that cannot be estimated based on existing sources of data. The utilization of machine learning techniques to predict these performance metrics is also discussed.

In 2019, nation-wide bus ridership attained its lowest level ever recorded in history. We investigate the change in bus ridership over time in four cities using passenger count data at 50,000 stops. We find consistent results in all four cities: 1) the proportion of local residents who are white is correlated with a decline in bus ridership 2) although the most frequent routes have the most passenger boardings per trip, ridership is inelastic to frequency. These results shed light on the causes of bus ridership decline and help identify strategies to reverse the trend.

Autonomous vehicles (AVs) may hold health and safety benefits for older drivers (> 65 years old), if they accept and adopt this emerging technology. The purpose of this study was to compare older drivers’ perceptions before and after riding in an on-road autonomous shuttle (SAE Level 4) and a driving simulator in autonomous mode (SAE Level 4). Primary objectives completed in this study included survey development and validation, establishing congruence between on-road route and simulator scenario, and exploring older drivers’ perceptions of AVs. The findings provide a vital perspective into the barriers and facilitators for accepting and adopting AV technologies.
Technology Influence on Travel Demand and Behaviors

The rapid technological developments in the 21st century created new opportunities for shared-use economy applications in the US and around the globe. In the recent years, many large- and medium-sized city markets have experienced increases in the availability and popularity of Transportation Network Companies (TNCs), for-hire vehicles, and on-demand services such as UberX and Lyft. However, it is still not clear how availability of smartphone-based traveler information services influence travel choices and what are the impacts from mode choice changes on transportation network operations. This seminar presents findings from a study that investigated the influence of ride-sourcing on transportation users’ choices and behaviors in the Birmingham, AL region. The study a) documented Birmingham metro transportation users’ attitudes, choices, and behavioral trends and b) examined the feasibility of using agent-based simulation modeling to quantify the impacts of mode choice shift due to ride-sourcing on local and regional congestion. The seminar introduces the study methodology, presents findings and conclusions, and discusses next steps.
Fly-By Image Processing for Real Time Congestion Mitigation

The fly-by system consists of a “flock” of interconnected, self-managed drones equipped with lightweight navigation, and perching mechanism allows the drone to record videos from fixed points. Image processing techniques are used to detect traffic parameters from the recorded videos. On the other hand, Traffic simulations models will be utilized to develop the database necessary in developing and training the Traffic Model-Based Image Processing (T-MBIP) algorithm. These simulations are focused on traffic congestions. Once the traffic parameters are detected it will be compared with the congestion case to obtain if the congestion is approached or not.
