Speed management is an essential tool in a sustainable transportation system that can reduce conflicts with vulnerable users such as bicyclists and pedestrians. The Federal Highway Administration (FHWA) published Speed Management Toolkits (SMTs), which list conventional engineering countermeasures, their potential effects measured as Crash Modification Factors, and implementation strategies. The advancement of computer science, communication skills, and vehicle manufacturing technologies brings the potential for advanced speed management and reducing collisions with vulnerable users. However, many new technologies have not been directly connected to speed management, and their effectiveness in enhancing vulnerable user safety has not been well studied, documented, and implemented. This project will conduct a literature review and expert survey to investigate the most promising emerging technologies for advanced speed management, such as Connected and Autonomous Vehicle technologies, Advanced Driver-Assistance System messaging, Advanced Traveler Information Systems, Advanced Vehicle Location, remote sensing and detection technologies for pedestrians, bicycles, and other vulnerable users; advanced signal timing technologies, etc. The research team will select testbeds mainly in the Third Ward of Houston, a diverse black community in Houston, with the support of local transportation agencies and the community. Simulation scenes will be designed for the tests in driving and bicycle simulators at Texas Southern University. Subjects will be recruited, and the effectiveness of the emerging technologies-based speed management countermeasures will be evaluated. Further field test plans, FHWA Speed Management Toolkit updates, and implementation strategies will be recommended. This project will help better manage travel demand for a more sustainable transportation system.
