Lecture Presentation on: Improve the Level of Service of Free-Floating Bike Sharing - its Connectivity with Freight Applications

By: Yu Zhang, Ph.D., Associate Professor, Department of Civil and Environmental Engineering, University of South Florida (USF) 

Dr. Zhang

Abstract: Bike Sharing is a sustainable mode of urban mobility, not only for regular commuters but also for casual users and tourists. Free-floating bike sharing (FFBS) is an innovative bike-sharing model, which saves on start-up cost, prevents bike theft with built-in GPS, and allows users to reserve bikes via smart phone APP. Nevertheless, the flexibility of FFBS also brings challenges to its operational management. At USF, we launched Share-A-Bull FFBS in 2015 and our research team has since worked closely with service provider to tackle the challenging problems. We study historical biking trajectory data of FFBS users for understanding their mobility patterns and the correlations with environment variables and the interactions of those variables. The outcomes provide insights on system design and operations, e.g. hub regions of bike sharing program, time for conducting static or dynamic rebalancing, and time available for different types of rebalancing, etc. We also propose a MILP and heuristic solution algorithm to solve bike rebalancing for FFBS. The experimental results show that the proposed algorithm outperforms existing methods. A smart phone app is developed for practical usage of the research results in daily operations as well.

Lecture presentation on: Data-Based Decision Support: A Journey from Data to Information

By: Yan Xiao, Ph.D., P.E., Research Associate, Florida International University     


Abstract: With the wide deployment of ITS devices, big data can be collected from multiple sources, such as point detector, Bluetooth reader, Wi-Fi reader, connected vehicles, and so on. How to extract useful information from large amount of data is an urgent task facing transportation agencies. This presentation will provides a brief review of existing data collection technologies, discusses data processing procedures, and demonstrates how these data can be applied to support both planning and operational level decisions.

Lecture presentation on: Evaluation of pedestrian and Bicyclist performance Measures by Using Crowd Monitoring Technologies in Southeast Florida

By: Bratislav Ostojic, Research Associate at Florida Atlantic University


Abstract: In order to create safer and attractive facilities for pedestrians and bicyclists it is necessary to collect data about activities of these multimodal users and develop performance measures which can be monitored and maintained. Manual traffic data collections are time and resource intensive and transportation agencies constantly seek for new technologies to collect data about multimodal users. Once such data are collected it is necessary to combine them in meaningful performance measures which will reflect safety, level of service and comfort of the non-motorized transportation users. Recent advances in crowd-monitoring and video feature extraction technologies have offered some opportunities to collect more and better data about pedestrians, bicyclists, and others users of shared facilities in urban transportation networks. This presentation presents findings from a study where data collected by two popular, yet different, crowd monitoring technologies (Placemeter and Strava) were assessed for their feasibility to collect data of the pedestrians and bicyclists in a number of locations in Southeastern Florida. In addition to the assessment of data collection, the FAU research team has also developed a set of performance measures based on the Highway Capacity Manual (HCM), in order to quantify the quality of provided services to the different transportation modes.

Lecture presentation on: Opportunities for enhancing the robustness and functionality of the dedicated short range communications (DSRC) infrastructure through the use of satellite digital audio radio service (DARS)

By: Richard A. Michalski, Principal Chief Engineer at SiriusXM Innovation Center


Abstract: The USDOT has committed to using DSRC technologies for active safety involving vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications, which relies on trusted certificates, sharing accurate position and velocity with nearby vehicles, and sharing information about road conditions. Satellite digital audio radio service (SDARS) provides nearly ubiquitous coverage over North America and is a proven technology with reliable coverage and high-penetration in vehicles. SDARS can enhance the reliability and effectiveness of DSRC infrastructure in several ways, including certification revocation list (CRL) distribution, distribution of traveler information messages (TIMs), distribution of GPS ephemeris data, and provision for alternative approaches to certificate distribution.

Lecture presentation on: Guidance for identifying corridor conditions that warrant deploying transit signal priority and queue jump.

Abstract: Our roadways are getting more congested as large number of cars are entering the transportation system due to rise in population. The high volume of vehicles and numerous signalized intersection the traffic congestion is causing huge problems to schedule reliability. As transportation demand is increasing various road networks are facing increasing congestion. Transportation management measures that provide more capacity out of the prevailing resources must be explored in order to obtain financially viable transportation solutions. Transit supportive strategies include intersection treatments such as transit signal priority (TSP), special signal phasing, queue jump lanes and signals. To mitigate the high density congestion transit signal priority is the significant solution. Transit signal priority is providing solutions according to many variables, and it is pursuing a number of valuable objectives such as: reduced transit travel times, better schedule adherence, better transit efficiency, and increased road network efficiency by car mobility. TSP technique has been applied to improve transit service quality and increase bus ridership.
