Data-Driven Mobility Strategies for Multi-Modal Transportation
Yao-Jan Wu
Xianfeng Yang , Sirisha Kothuri
By using various modes (e.g., walking, cycling, automobile, public transit, etc.), multi-modal transportation systems are effective in increasing people’s travel flexibility and reducing congestion. Hence, it is critical to understand how roadway s ...

Data and Methodological Issues in Assessing Multimodal Transportation Impacts for Urban Development
Kristina Currans
In 1976, the Institute of Transportation Engineers (ITE) compiled their first Handbook of guidelines and methods for evaluating development-level
transportation impacts, specifically vehicular impacts (Institute of Transportation Engineers 1976). De ...

Improving Walkability Through Control Strategies at Signalized Intersections
Sirisha Kothuri
Christopher Monsere , Edward Smaglik
The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle ...

Using High-Resolution Bus Detection Data to Improve Travel Time Prediction and Identify Urban Congestion Spots
Miguel Figliozzi
Robert Bertini
Most urban vehicle miles traveled take place along arterials and collector streets. Arterials and collector streets are also essential to provide accessibility and provide mobility for public transportation fleets; these roadways constitute the back ...

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors
Miguel Figliozzi
Christopher Monsere
Transit service reliability is important to both passengers and transit agencies. Slow and unreliable transit service may increase transit user costs in the short term and reduce transit mode share and ridership in the long term, which in turn may le ...

Lightweight Buckling Restrained Brace Prototype Evaluation
Peter Dusicka
Buckling restrained brace (BRB) is a structural component that has been developed to provide known and repeatable strength in both tension and compression. Over the last couple ofdecades, BRBs have seen broad adoption in buildings in areas ofmoderate ...

Evaluation of Bike Boxes at Signalized Intersections: Phase 2
Christopher Monsere
Analyses of motor vehicle and police-reported crash data reveal that nearly 68 percent of bicycle crashes in Portland, Oregon occur at intersections (PDOT, 2004) which is consistent with national trends (Hunter et al., 1996). Hunter et al. (1996) ...
