Webinar: Modeling Freeway Traffic in a Mixed Environment: Connected and Human-Driven Vehicles

Thursday, January 24, 2019, 10:00am to 11:00am PST
Webinar: Modeling Freeway Traffic in a Mixed Environment: Connected and Human-Driven Vehicles - Terry Yang

 

OVERVIEW

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are introduced to the speed equation for accounting CV speed impacts. Then extended Kalman Filter is employed to update both model parameters and friction factors in real-time. By using CVs trajectory data as measurements, the difference between CV average speed and overall traffic mean speed will be fully accounted. The proposed model will serve as a basis for designing CV-based traffic control function, such as speed harmonization, on highways.

Friday Transportation Seminar (PBOT Edition): The Portland E-Scooter Experience

Friday, February 1, 2019, 11:30am to 1:00pm PST

Friday Transportation Seminars at Portland State University have been a tradition since 2000. With the start of 2019, we're changing it up a bit! We'll still offer the "classic" Friday Seminar series as a for-credit PSU course each fall, while in the Winter and Spring terms we're offering biweekly presentations and opportunities to gather, enjoy refreshments and make connections. Friday Transportation Seminars will start at 11:30 am and go to 12:30 pm, with additional discussion over coffee and donuts (protect the planet—bring a mug!) from 12:30 to 1:00 pm.

Every other month, as part of this new format, we're teaming up with the Portland Bureau of Transportation (PBOT) to bring you special "PBOT Editions" of Friday Transportation Seminars—featuring guest speakers from PBOT—merging the Friday Transportation Seminar series and the long-standing PBOT Lunch & Learn series.

Friday Transportation Seminar: The Success of an Integrated Mobility Strategy: Lessons from the Netherlands for the Pacific West Coast

Friday, February 15, 2019, 11:30am to 1:00pm PST

Friday Transportation Seminars at Portland State University have been a tradition since 2000. With the start of 2019, we're changing it up a bit! We'll still offer the "classic" Friday Seminar series as a for-credit PSU course each fall, while in the Winter and Spring terms we're offering biweekly presentations and opportunities to gather, enjoy refreshments and make connections. Friday Transportation Seminars will start at 11:30 am and go to 12:30 pm, with additional discussion over coffee and donuts (protect the planet—bring a mug!) from 12:30 to 1:00 pm.

EVENT OVERVIEW

The Netherlands sets the standard for their multimodal connectivity. It has world's highest use of cycling and an integrated mobility network with an efficient transport system. During this seminar, Lucas will tell more about the Dutch Approach and how this could be applied to the American transportation context. 

Lucas will use the case of the Bay area to show this. The Bay Area in California currently faces massive challenges in transportation because of the enormous growth of the region. With the use of a new innovative modelling tool, the Move Meter (...

Friday Transportation Seminar: Public Transportation and New Mobility

Friday, March 8, 2019, 11:30am to 1:00pm PST

Friday Transportation Seminars at Portland State University have been a tradition since 2000. With the start of 2019, we're changing it up a bit! We'll still offer the "classic" Friday Seminar series as a for-credit PSU course each fall, while in the Winter and Spring terms we're offering biweekly presentations and opportunities to gather, enjoy refreshments and make connections. Friday Transportation Seminars will start at 11:30 am and go to 12:30 pm, with additional discussion over coffee and donuts (protect the planet—bring a mug!) from 12:30 to 1:00 pm.

EVENT OVERVIEW

New mobility options such as bike share, scooters, and transportation network companies (e.g. Uber) are proliferating across the United States and beyond. Early research has shown that while the private automobile continues to be the main competition for transit, new mobility options may also be siphoning off some riders. In this seminar, we will explore what the role of public transportation should be in this era of rapidly expanding private transportation options. We will also examine how private transportation could be harnessed to help public transportation succeed and allow for cities to meet their...

ChickTech Workshop: Design Online Interactive Maps with TREC

Saturday, March 9, 2019, 8:00am to 5:00pm PST

Registration is open to female and female-identified students currently in high school.

The spatial mapping of events has been evolving as a major method of analysis for centuries. Join us at this one-day workshop for high school girls to become familiar with these concepts, by working with vehicle crash data from the City of Portland.

The workshop, held in the Intelligent Transportation Systems (ITS) lab of PSU’s Engineering Building, consists of a morning instruction session and an afternoon applied activity using their newfound GIS skills. Students will be introduced to the basic elements of ArcGIS — including importing data, exploring the variables and searching through the spatial database, and processing the data in different ways.

The day also includes a lunchtime walking tour of active transportation infrastructure around the Portland State University campus. By the end of the day you will have a working understanding of spatial mapping and new ideas for how you can apply them to your city!
