Estimation Of The Mobility Benefits Of Ramp Metering, Henrick Joseph Haule

FIU Electronic Theses and Dissertations

Transportation agencies are implementing traffic management strategies to improve mobility and safety on freeways. Ramp metering is a traffic management strategy deployed to mitigate congestion on freeways using traffic signals installed at entrance ramps to control and regulate vehicle entry onto the freeway mainline. Estimating the mobility benefits of ramp metering is critical to determine the strategy's effectiveness and inform the decision-making process regarding its deployment.

However, the extent of the impact of ramp metering on recurrent congestion varies across studies. Among the reasons for the inconsistencies are the limitations of conventional methods for evaluating benefits, including the before-and-after approach, …

Estimation And Prediction Of Mobility And Reliability Measures Using Different Modeling Techniques, Fatema Hoque Farzana

FIU Electronic Theses and Dissertations

The goal of this study is to investigate the predictive ability of less data intensive but widely accepted methods to estimate mobility and reliability measures. Mobility is a relatively mature concept in the traffic engineering field. Therefore, many mobility measure estimation methods are already available and widely accepted among practitioners and researchers. However, each method has their inherent weakness, particularly when they are applied and compared with real-world data. For instances, Bureau of Public Roads (BPR) Curves are very popular in static route choice assignment, as part of demand forecasting models, but it is often criticized for underperforming in congested …

2013-14 Indiana Interstate Mobility Summary, Steve M. Remias, Howell Li, Darcy M. Bullock

JTRP Posters

These posters highlight the speed and mobility metrics on four of Indiana’s interstates (I-94, I-65, I-465, and I-70). The posters are part of the effort by the Indiana Department of Transportation to characterize mobility concerns on the statewide interstate system.

An Analysis Of The Travel Patterns And Preferences Of The Elderly, Sujan Sikder

USF Tampa Graduate Theses and Dissertations

The number of elderly is increasing; to meet their transportation needs, it is important to clearly understand their travel patterns and preferences. Since travel patterns and preferences depend on socio-demographic and other factors, it is essential to identify these factors first to understand the travel behavior of the elderly. The main purpose of this thesis is to analyze the travel patterns and preferences of the elderly age 65 and above using 2009 National Household Travel Survey (NHTS) data. This thesis presents a detailed descriptive analysis of 2009 NHTS data to understand the travel patterns of the elderly. Along with a …

A Methodology For The Analysis Of Its Impacts On Mobility, Air Quality, And Land Use, Kumares C. Sinha, Srinivas Peeta, Muhammed Amer Sultan, Kamalakar Poonuru, Nadine-Jenelle K. Richards

JTRP Technical Reports

The Indiana Department of Transportation (INDOT) is currently implementing (or has implemented) several components of Intelligent Transportation Systems (ITS). This includes a mini Advanced Traffic Management Systems (ATMS) implemented on a three-mile stretch of the Borman Expressway to evaluate advanced non-intrusive sensor systems and the associated communication infrastructure for the installation of a full-scale ATMS on the 16-mile stretch of the Borman Expressway. Potential specific ITS technologies that are either being implemented or are being considered include pre-trip information, en-route information, variable message signs, and Hoosier Helpers. It is expected that the implementation of various ITS technologies on the Borman …
