Impact Of Last Mile Parking Availability On Commercial Vehicle Costs And Operations, Miguel Figliozzi, Chawalit Tipagornwong
Impact Of Last Mile Parking Availability On Commercial Vehicle Costs And Operations, Miguel Figliozzi, Chawalit Tipagornwong
Civil and Environmental Engineering Faculty Publications and Presentations
This research analyses how parking availability levels affect commercial vehicle parking costs and operations in congested urban areas. Unlike passenger vehicles, parking availability has an impact on route characteristics and commercial vehicle fleet sizes. Hence, commercial vehicles parking costs cannot be captured solely by estimating delays and/or the cost of parking fines. This research combines logistics, queuing, and optimization models to study the impact of last mile parking availability on commercial vehicle costs and operations. Scenarios are built to study the impact of parking availability on typical less-than-truckload (LTL) and courier service costs. Results indicate that parking availability levels do …

Putting The Fun Before The Wonk: Using Bike Fun To Diversify Bike Ridership, Lillian Karabaic
Putting The Fun Before The Wonk: Using Bike Fun To Diversify Bike Ridership, Lillian Karabaic
PSU Transportation Seminars
The Community Cycling Center has been at the business of broadening access to bicycling for 22 years. Far before anyone was talking about "equity" in the world of bike commuting and advocacy, the Community Cycling Center was working directly with youth of color to make biking accessible. How have they been doing it? What have they learned?
Lillian Karabaic explains the secret to the Community Cycling Center's work to build bike capacity in underserved neighborhoods: bike fun. Many bike advocacy organizations look down at making bikes fun because they think it lowers the status of serious transportation to "recreation" or …
Rerouting Mode Choice Models: HOw Including Realistic Route Options Can Help Us Understand Decisions To Walk Or Bike, Joseph Broach
Rerouting Mode Choice Models: HOw Including Realistic Route Options Can Help Us Understand Decisions To Walk Or Bike, Joseph Broach
PSU Transportation Seminars
For a number of reasons—congestion, public health, greenhouse gas emissions, energy use, demographic shifts, and community livability to name a few—the importance of walking and bicycling as transportation options will only continue to increase. Currently, policy interest and infrastructure funding for nonmotorized modes far outstrip our ability to successfully model bike and walk travel. In the past five years, we have learned a lot about where people prefer to bike and walk, but what can that tell us about whether people will bike or walk in the first place? The research presented here is designed to start bridging the gap …

Towards Effective Design Treatment For Right Turns At Intersections With Bicycle Traffic, David Hurwitz, Christopher Monsere
PSU Transportation Seminars
The overall goal of this research was to quantify the safety performance of alternative traffic control strategies to mitigate right-turning-vehicle/bicycle collisions, often called "right-hook" crashes, at signalized intersections in Oregon.
A two stage experiment was developed in the OSU high-fidelity driving simulator to investigate the causal factors of right-hook crashes at signalized intersections with a striped bike lane and no right-turn lane, and to then identify and evaluate alternative design treatments that could mitigate the occurrence of right-hook crashes.
Experiment 1 investigated motorist and environmental related causal factors of right-hook crashes, using three different motorist performance measures: (1) visual attention, …
An Activity-Related Land Use Mix Construct And Its Connection To Pedestrian Travel, Steven R. Gehrke
An Activity-Related Land Use Mix Construct And Its Connection To Pedestrian Travel, Steven R. Gehrke
PSU Transportation Seminars
Land use mix is a central smart growth principle connected to active transportation. This presentation describes the indicators of local land use mixing and their association with pedestrian travel in Oregon’s Willamette River Valley. It argues that land use mix is a multidimensional construct reflected by the complementarity, composition, and configuration of land use types, which is positively linked to walk mode choice and home-based trip frequency. Findings from this study underline the conceptual and empirical benefit of analyzing this transportation-land use interaction with a landscape pattern measure of activity-related composition and spatial configuration.
The presentation for this seminar was …

The End Of The Road: The State Of Urban Elevated Expressways In The United States, Daniel Waqar
Brookings Mountain West Publications
In a January 2016 meeting, the Clark County Commission heard a proposal from the County Public Works Department about a $200 million plan to build two urban elevated expressways constructed above existing roadways, potentially linking McCarran International Airport with the Las Vegas Strip’s resort corridor. Commissioners lauded the project with a “high degree of confidence” for funding sources and praised the “magnificent way of moving traffic” and “out of the box thinking” of these urban elevated expressways. Yet the positive feedback that County Commissioners showered on this proposal flies in the face of decades of history on urban elevated expressways. …

Utilizing High Resolution Bus Gps Data To Visualize And Identify Congestion Hot-Spots In Urban, Nicholas B. Stoll, Travis B. Glick, Miguel Figliozzi
Civil and Environmental Engineering Faculty Publications and Presentations
Congestion and travel delay on urban roadways can influence the roadways’ operating costs and service attractiveness. This research used high-resolution bus data to examine sources of delay on urban arterials. A set of tools was created to help visualize trends in bus behavior and movement; these tools allowed larger traffic trends to be visualized along urban corridors and streets. With buses as probes and examining aggregated bus behavior, contoured speed plots were used to understand the behavior of roadways outside the zone of influence of bus stops. Speed plots were used to discover trends and travel patterns with only a …

Developing Seamless Connections In The Urban Transit Network: A Look Toward High-Speed Rail Interconnectivity, Tingting Yu
UNLV Theses, Dissertations, Professional Papers, and Capstones
In the past, the studies in the U.S. on high speed rail have been on economic impact. Recently, there are a few studies on the multimodal connectivity at high speed rail stations. High speed rail stations are viewed as hubs that are connected by different modes of public transportation by which passengers are transported to their destinations. How and in which way these different modes are connected to high speed rail stations influence the ridership of high speed rail stations. As the development of high speed rail system in the U.S. has come to the stage for actual design and …
Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster
Evaluating The Level-Of-Service Of Protected Bike Lanes, Nick Foster
PSU Transportation Seminars
Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods …

Trick Or Treat(Ment)? : Impact Of Route-Level Features On Walk And Bike Decisions, Joseph Broach
PSU Transportation Seminars
Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?
Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike …
