Technology is constantly evolving and changing the way people interact with one another, work, do business, travel, and even how they buy groceries. New and emerging technologies offer the potential for a safer, more efficient transportation system; more connectivity globally and locally; and streamlined business practices. However, increased reliance on technology brings other challenges to the forefront like cybersecurity and data privacy. Transportation partners need to make wise decisions today to prepare for this future.
Natural hazards, cyberattacks, and other events can have significant and unexpected impacts on Florida. Simultaneously, trends such as sea level rise and global economic shifts can lead to progressive challenges. These events and trends can result in unanticipated transportation system disruptions and increasing constraints on infrastructure, impeding access to reliable mobility. The impact on the lives of residents and visitors and the flow of business and trade can be extensive. It is critical to prepare Florida’s transportation system to be adaptive in the face of these events and trends. Planning for resilience leverages our understanding of potential hazards to mitigate risk, make wiser investment decisions, and provide more reliable transportation.

This presentation will talk about the impacts of technologies on freight agent behavior and demand pattern in near future. The presentation will discuss the special features of the new freight demand, and how to get prepared for these new trends from the perspectives of data acquisition, modeling, and policy making.

This presentation will provide an overview of San Francisco’s Vision Zero policy to eliminate traffic deaths and reduce severe injuries on City Streets. Six years in to San Francisco’s Vision Zero commitment, this presentation will provide insights into what it will take to eliminate traffic deaths, the critical need to elevate equity in traffic safety initiatives, and the key role of public health data and evidence.

Driving behaviors and driving safety involve complex interactions between the driver, their vehicle and the environment. Driving behaviors account for approximately 95% of crashes, but interventions to reduce known risks often don’t reach the target audience. The presenter will discuss strategies employed by the UC San Diego Center for Human and Urban Mobility to improve driving safety.

As recommended by California’s Strategic Highway Safety Plan (SHSP), Caltrans is working to develop a pedestrian and bicyclist safety improvement program. This presentation by Rachel Carpenter provided an overview of what has been completed since the program’s inception in 2016 as well as next steps. Specifics behind the below listed efforts were shared.
- the 2016 (Pilot) Pedestrian Collision Monitoring Program,
- the 2018 (Pilot) Bicyclist Collision Monitoring Program,
- the 2020 Pedestrian Collision Monitoring Program,
- pedestrian and bicyclist safety training, and
- modifications to California Manual on Uniform Traffic Control Devices (CA MUTCD) related to pedestrian and bicyclist safety and operations.

Background: The Integrated Transport and Health Impacts Model (ITHIM) is a scenario-based risk assessment tool that quantifies the health benefits and harms of physically active travel (walking and cycling), road traffic injuries, and fine particulate air pollution in urban transportation systems.
Methods: Descriptive statistics on travel patterns, physical activity, traffic injuries, and car emissions were derived from statewide travel and health surveys, collision databases, and outputs from regional travel demand and emissions models. The change in disease burden was measured in deaths and disability adjusted life years (DALYs) based on dose–response relationships from meta-analyses and the distributions of physical activity and traffic injuries. Alternative scenarios were measured against baseline travel patterns experienced in each major California region. Alternative scenarios included increases in active travel from baseline to 20 median minutes/person/day, apportioned entirely to walking (“all walk”), cycling (“all cycle”), and or transit-related active travel (“all transit”). The health benefits and greenhouse mitigation of these scenarios were compared to those of the preferred scenarios regional transportation planning agencies. These agencies are mandated to demonstrate greenhouse gas reductions in their transportation plans (“Sustainable Communities Strategies (SB375)”, which emphasize transit expansion to achieve this goal.
Results:The preferred scenarios increased statewide active transport from 41 to 54 min/person/week, which was associated with an annual decrease of 890 deaths and 15,053 DALYs. The ambitious, maximal alternatives increased population mean travel duration to 283 min/person/week for walking, bicycling, or transit and were associated a reduction in deaths and DALYs from 2.5 to 10 times greater than the California preferred scenarios. The alternative with the largest health impact was bicycling, which led to 8,349 fewer annual deaths and 141,597 fewer DALYs, despite an increase in bicyclist injuries. With anticipated population growth by 2040, no alternative achieved decreased carbon emissions, but bicycling had the greatest potential for slowing their growth.
Conclusions: Expansion of transit confers important health benefits through active transport and meets important societal goals for destination accessibility. However, expansion of walking and cycling, independently of transit, can play a larger role in improving population health.

Collective properties of traffic flow, such as its equilibrium, aggregate dynamics and stability, are determined by attributes of agents (i.e. drivers/vehicles) as well as how the agents interact. Understanding connections between the two is crucial to control and operations, e.g. towards designing mechanisms to make mixed traffic flow of autonomous and human-driven vehicles self-organize and self-stabilize. In this talk, Jia Li presented recent research in this direction. In the first part, Li provided an explicit characterization of equilibriums attainable by heterogeneous traffic flow in multilane settings, where one class of agents are “type-sensitive”, a property that autonomous vehicles may likely be endowed with. In the second part, Li presented simulation evidence along with a heuristic analysis towards explaining spontaneous platoon formation in heterogeneous traffic flow and the role of opportunistic agent behaviors. Finally, Li discussed implications of these results from a control perspective.

There are tremendous opportunities in Hillsborough County at this time. We can create a safe, sustainable transportation network and build the kind of vibrant, walkable places that bring opportunity, economic development, and support a higher quality of life for our residents. Commissioner Kemp is looking forward to joining other women leaders in transportation in Hillsborough County to have a conversation about how they can work together to accomplish these goals. She will be joined by Jean Duncan, P.E. Director of Transportation and Stormwater Services for the City of Tampa, Cassandra Borchers, AICP, Chief Development Officer of PSTA, and Beth Alden, AICP, Executive Director of Hillsborough County MPO.

New evidence linking built and natural environment features with physical activity, obesity, diabetes, cardiovascular disease, stress, and sense of community will be presented. These finding are based on large scale health surveillance databases (40,000-50000 N) with address information spatially linked with detailed measures of regional transportation accessibility, walkability metrics, and green space. Results have been integrated into decision-support scenario planning tools (California and National Public Health Assessment Models) designed to predict health impacts of contrasting land use and transportation investment proposals at the neighborhood, corridor, and regional scale.

Florida’s Strategic Intermodal System (SIS) represents the state’s largest and most significant transportation facilities including airports, spaceports, seaports, rail corridors, passenger terminals, transit, waterways, and highways. The SIS serves as the primary avenue for implementing Florida’s long-range transportation vision and SIS facilities receive the highest priority for transportation capacity improvements. Florida Department of Transportation (FDOT) Systems Implementation Office Manager Huiwei Shen, SIS Planning Manager Chris Edmonston, and SIS Administrator Jennifer King shared how the SIS plans for multimodal facilities.
