PLANNING FOR PEDESTRIANS IN AN AUTOMATED AND CONNECTED FUTURE


SPEAKER:

PROFESSOR KELLY J. CLIFTON

Portland State University, U.S.A.


DATE:

23 OCTOBER 2018 (TUESDAY)


TIME:

19:00 - 20:00

VENUE:

LECTURE THEATRE P2, LG1/F, CHONG YUET MING PHYSICS BUILDING, THE UNIVERSITY OF HONG KONG


ORGANISED BY:

Institute of Transport Studies, The University of Hong Kong


ABSTRACT:

There is much interest of late in the promise of technologies to provide safe, efficient, and comfortable mobility. Most of this discussion has focused on autonomous and connected vehicles and the benefits for urban travel for passengers in automobiles and various forms of shared mobility options, including transit. With the exception of the potential to improve safety and reduce injuries and deaths, less attention has been paid to how these technologies will impact the pedestrians and the urban environmental conditions that support walking. As with most discussions of the future, this talk will begin with a focus on the past. The presentation will place walking, our oldest and most basic form of mobility, in its historic context and review the accommodations for pedestrians throughout history. Then, the talk will shift to the current state of knowledge about walking in the city and the opportunities and threats to this mode. Next, the potential implications of an automated and connected future on walking will be presented. The challenge for transport planning is to craft policies and interventions to preserve this important mode of transport among the introduction of new forms of mobility. The talk will conclude with a research program that can inform and promote this multimodal agenda.

DYNAMIC TRAFFIC ASSIGNMENT: HISTORY, RECENT RESULTS AND UNANSWERED QUESTIONS


SPEAKER:

PROFESSOR TERRY L. FRIESZ

The Pennsylvania State University, U.S.A.


DATE:

08 JUNE 2018 (FRIDAY)


TIME:

19:00 - 20:00

VENUE:

WANG GUNGWU THEATRE, GRADUATE HOUSE, THE UNIVERSITY OF HONG KONG


ORGANISED BY:

Institute of Transport Studies, The University of Hong Kong


ABSTRACT:

This talk begins by discussing the intellectual history of dynamic traffic assignment (DTA). We then review the DTA modeling paradigms available today. We also hypothesize how travel behavior over vehicular networks may change due to innovations in information technology. This leads us to conjectures about the form of new DTA models and associated computational methods.

ASSESSMENT OF THE ROAD SAFETY BENEFITS OF CONNECTED VEHICLE TECHNOLOGIES


SPEAKER:

PROFESSOR MOHAMED ABDEL-ATY

Trustee Chair, Pegasus Professor and Department Chair, University of Central Florida

ABSTRACT:

Connected Vehicle (CV) technologies are believed to have a large effect on traffic safety. For now, it is important to determine the expected effect that CV technologies would have in reducing crashes when all vehicles are equipped with them? Which crash types could these technologies make the greatest benefit? The answers to these questions are meaningful because they could provide important guidance for CV-related policies, research, resource allocation, manufacturing and promotion of these systems. At present little work has been done toward answering these questions. Actually there are plenty of studies which focus on separate safety performance of a single or several CV technologies, but few in the literature have tried to integrate all CV-related studies to make a comprehensive and general safety benefit estimation. In this presentation, we provide an introduction about CV, we make a general crash avoidance effectiveness framework of CV technologies, then we apply the crash avoidance effectiveness framework to the total crash population to estimate a total safety benefit of CV technologies.

​

The presentation also addresses some of the current CV-related studies by the presenter’s team. The effectiveness of Connected Vehicle (CV) technologies in adverse visibility conditions using microscopic traffic and driving simulation. Traffic flow characteristics deteriorate significantly in reduced visibility conditions resulting in high crash risk. We apply CV technologies on a segment of Interstate I-4 in Florida to improve the traffic safety under fog conditions. Two types of CV approaches (i.e., connected vehicles without platooning (CVWPL) and connected vehicles with platooning (CVPL)) were applied to reduce the crash risk in terms of three surrogate measures of safety. This study implemented Vehicle-to-Vehicle (V2V) communication technologies of CVs to acquire real-time traffic data using the microsimulation software VISSIM. The model performance was evaluated under different CV market penetration rates (MPRs). The study also proposed a traffic safety improvement approach by Variable Speed Limit (VSL) strategy to reduce secondary crash risk under fog conditions. The VSL strategy was tested under both connected-vehicle (CV) environment and non-CV environment. Another study used driving simulation to test the effectiveness of V2I and V2V and the design of heads up display.


While the presentation will focus on the safety benefits of CV, it will also address relevant issues in traffic operation, big data, and active traffic management.
