Impacts Of Low-Speed Vehicles On Transportation Infrastructure And Safety, Katharine M. Hunter-Zaworski, Linda Cornell
Impacts Of Low-Speed Vehicles On Transportation Infrastructure And Safety, Katharine M. Hunter-Zaworski, Linda Cornell
TREC Final Reports
There are increasing numbers of low-speed electric vehicles (LSVs) on public roadways. These vehicles are designed to be used within protected environments and on roadways with a maximum posted speed of 25 mph. Currently these vehicles are not subject to the same federal requirements for occupant protection as passenger cars. This research project investigated safety standards, operating regulations, and LSV manufacturer materials from sources around the world. The purpose of the research was to determine positive and negative impacts that LSVs, including Neighborhood Electric Vehicles (NEVs) and Medium Speed Electric Vehicles (MSEVs), are likely to have for the Oregon Department …
Performance Enhancement Of Bridge Bracing Under Service And Extreme Loads, Peter Dusicka, Max Taylor Stephens, Kate Fox-Lent
Performance Enhancement Of Bridge Bracing Under Service And Extreme Loads, Peter Dusicka, Max Taylor Stephens, Kate Fox-Lent
TREC Final Reports
As truck loads continue to get bigger, the demand on many aging bridges increases. Slender steel structural elements widely used in bridge superstructures and braced substructures to resist these loads are built primarily for tension, however, and can buckle under compressive loads. Portland State University associate professor Peter Dusicka set out to develop and demonstrate the concept of retrofitting bridge brace elements with fiber reinforced composites in order to provide restraint against buckling. The advanced materials consisted of a combination of fiber reinforced polymer (FRP) composite pultruded sections and wet lay-up wraps intended to be applied in the field. This …
Analysis Of Bus Collision Incidents Using Transit Its And Other Archived Operations Data, James G. Strathman, Paul Herman Wachana, Steve Callas
Analysis Of Bus Collision Incidents Using Transit Its And Other Archived Operations Data, James G. Strathman, Paul Herman Wachana, Steve Callas
TREC Final Reports
This report analyzes factors contributing to bus operations safety incidents at TriMet, the transit provider for the Portland Oregon metropolitan region. The analysis focuses on 4,631 collision and non-collision incidents that occurred between 2006 and 2009. Empirical analysis of these incidents draws on a wide array of operator-level data recovered by transit ITS technologies in combination with information from TriMet’s human resources, scheduling, and customer relations databases. Incident frequencies are estimated in relation to operators’ demographic characteristics, employment status, assigned work characteristics, service delivery and performance indicators, temporal factors, and customer information. Apart from identifying factors that are empirically related …
Empirical Observation Of The Impact Of Traffic Oscillations On Freeway Safety, Christopher M. Monsere, Soyoung Ahn
Empirical Observation Of The Impact Of Traffic Oscillations On Freeway Safety, Christopher M. Monsere, Soyoung Ahn
TREC Final Reports
Traffic oscillations are typical features of congested traffic flow that are characterized by recurring decelerations followed by accelerations (stop-and-go driving). The negative environmental impacts of these oscillations are widely accepted, but their impact on traffic safety has been debated. This report describes the impact of freeway traffic oscillations on traffic safety. This study employs a matched case-control design using high resolution traffic and crash data from a freeway segment. Traffic conditions prior to each crash were taken as cases, while traffic conditions during the same periods on days without crashes were taken as controls. These were also matched by presence …
The Boulevard Study: From Arterial To Asset -- Examining The Role Of The Multi-Way Boulevard In Coordinated Transportation And Land Use Planning, Mark L. Gillem
The Boulevard Study: From Arterial To Asset -- Examining The Role Of The Multi-Way Boulevard In Coordinated Transportation And Land Use Planning, Mark L. Gillem
TREC Final Reports
Cities that were once considered the most-desired places to live or for businesses to locate are now seeking ways to unclog their increasingly congested roadways and regain their quality of life. U.S. Department of Transportation Strategic Plan Background Cities across the U.S. that are struggling with congestion resort to remedies that are increasingly difficult to implement. Adding capacity is a more challenging proposition given limited land availability, greater environmental constraints, and fiscal barriers. Replacing individual trips with transit has seen limited success and can typically only be justified at greater levels of density than many communities currently support. Multiway boulevards …
Financing Mechanisms For Capacity Improvements At Interchanges, James G. Strathman, Elizabeth Simmons
Financing Mechanisms For Capacity Improvements At Interchanges, James G. Strathman, Elizabeth Simmons
TREC Final Reports
This report examines the use of alternative local financing mechanisms for interchange and interchange area infrastructure improvements. The financing mechanisms covered include transportation impact fees, tax increment financing, value capture financing, local improvement districts, transportation corporations, state infrastructure banks, local option transportation taxes, fair share mitigation, and transportation concurrency. The financing alternatives are assessed in the context of Interchange Area Management Plans, which are required by the Oregon Transportation Commission, as well as in the context of the Oregon Department of Transportation’s responsibilities under the state’s Transportation Planning Rule.
Overlooked Density: Re-Thinking Transportation Options In Suburbia, Nico Larco
Overlooked Density: Re-Thinking Transportation Options In Suburbia, Nico Larco
TREC Final Reports
Suburban multifamily housing is an often overlooked housing typology that is the fasted growing housing market in the country and holds strong potential for achieving smart growth goals in suburbia. This housing type is ubiquitous throughout all regions in the nation, is a widespread example of density in suburbia, and is typically located next to commercial uses. The proximity between suburban multifamily housing and commercial uses creates the potential for nodes of concentrated activity, mixed use, and the possibility of substantial non-auto transport in suburbia. While this potential exists, the design of this housing type often follows an enclaved pattern …
