Public Perceptions Of The Midwest’S Pavements - Iowa - Phase Iii, David Kuemmel, Richard Robinson, Robert J. Griffin, Ronald C. Sonntag, James K. Giese

Transportation Research Center: Public Perception of Midwest Pavements

There are several objectives to this report. The first objective is to describe the sample with regard to the physical pavement data and three measures of driver satisfaction. In this section, the proportion of respondents who are satisfied with pavements on two-lane, rural, state highways will be examined and the distribution of pavement condition and roughness indices will be presented.

The second objective will be a short description of the highway segments and any differences in satisfaction found between regions and pavement types. This was done in Phase II in each state and a letter sent showing the results in …

Public Perceptions Of The Midwest’S Pavements - Minnesota - Phase Ii, Marquette University, Department Of Civil, Construction, And Environmental Engineering

Transportation Research Center: Public Perception of Midwest Pavements

This report covers Phase II of a three-phase pooled-fund project in Wisconsin, Iowa and Minnesota, to determine the perception/satisfaction levels of the driving public and how they correlate with the states’ physical data bases used to determine priorities for pavement improvements on rural, two-lane highways.

In Phase I, six focus groups were conducted in each state to determine the beliefs and issues about pavements that could be used to draft statewide questionnaires. Focus groups were held during the last half of 1996 in all three states. From the focus groups, a language used by the public to describe and differentiate …

2001 Wisdot Specifications - Construction Note, Marquette University, Transportation Research Center

Transportation Research Center: Noise & Texture Studies

For the past several years, Marquette University has been conducting a research study for WisDOT on tining patterns to reduce the objectionable tire/pavement whine. During the research study, WisDOT issued Construction Notes to implement the interim results of the research rather than tine the pavement according to Subsection 415.5.9.6.3 of the Standard Specifications.

In the completed study, Marquette University has determined that a skewed, randomly spaced, transversely tined surface results in the lowest levels of pavement whine while retaining the favorable friction characteristics achieved under the current specifications. The overall noise level is not reduced by skewed randomly tined surfaces. …

An Evaluation Of Age Effects On Driver Comprehension Of Flashing Traffic Signal Indications Using Multivariate Multiple Response Analysis Of Variance Models, Alexander Drakopoulos, Richard W. Lyles

Civil and Environmental Engineering Faculty Research and Publications

Objective: The objective of this experiment was to identify whether drivers comprehended traffic signals differently when turning left at signalized intersections where traffic signals were in “flashing mode” operation. Method:Multivariate multiple response analysis of variance models were used to analyze the simultaneous effects of displayed color combination, age, and geographical location on signal message interpretation. Data were gathered in a laboratory environment. Results: Left-turn and through-signal color combination had a significant effect on subject comprehension. Comprehension was found to be lowest for displays flashing red only, followed by displays flashing red on the left-turn, and yellow on the through-signal, …

Public Perceptions Of The Midwest’S Pavements - Minnesota - Executive Summary, David Kuemmel, Richard Robinson, Robert J. Griffin, Ronald C. Sonntag, James K. Giese

Transportation Research Center: Public Perception of Midwest Pavements

This report summarizes Minnesota results of a five year, Pooled Fund study involving the Wisconsin, Iowa, and Minnesota DOTs designed to 1) assess the public's perceptions of the departments’ pavement improvement strategies and 2) to develop customer-based thresholds of satisfaction with pavements on rural two lane highways in each state as related to the Departments’ physical indices, such as pavement ride and condition. The primary objective was to seek systematic customer input to improve the Departments’ pavement improvement policies by 1) determining how drivers perceive the departments’ pavements in terms of comfort and convenience but also in terms of other …

Public Perceptions Of The Midwest's Pavements - Phase I - Focus Group Content Analysis - Iowa, University Of Wisconsin - Extension, Wisconsin Survey Research Laboratory

Transportation Research Center: Public Perception of Midwest Pavements

This research is being conducted as part of a larger study of the public’s perceptions of state-maintained rural highway pavements in Wisconsin, Minnesota, and Iowa. Later stages of this project will involve interviewing residents of the three states by telephone to gather information about people’s concerns about the pavements in general and specific stretches of highways in particular. Information from this effort is expected to aid the states’ Departments of Transportation refine the standards used to set pavement reconstruction priorities to better meet the needs of residents.

Public Perceptions Of The Midwest’S Pavements - Wisconsin - Phase I (Winter Ride), Marquette University,Department Of Civil, Construction, And Environmental Engineering

Transportation Research Center: Public Perception of Midwest Pavements

The Wisconsin Winter Ride Survey was designed to determine the extent to which drivers were tolerant of the rougher ride of pavements on rural two-lane highways in the winter. Survey objectives, as such, were centered around this primary question of winter ride tolerance. A telephone survey was conducted by the Wisconsin Survey Research Laboratory (WSRL), which added questions to its quarterly Wisconsin Opinion Poll for the data collection period of January 15 to March 15, 1997. A similar survey focusing only on the topic of winter driving on rural highways was conducted in Minnesota during the same period. Random digit …

Development Of Comprehensive Subgrade Deflection Acceptance Criteria - Phase 3 Report, James Crovetti, Jay Schabelski

Transportation Research Center: Subgrade Deflection Studies

This report has presented the findings of Phase III of research conducted to aid in the development of subgrade deflection acceptance criteria for WisDOT. The reconfigured rolling wheel deflectomter (RWD), portable truck-mounted deflection measurement systems, and automated dynamic cone penetrometer (DCP) were utilized on subgrade construction projects throughout the 2000 construction season. Laboratory analysis of soil properties, including Proctor, CBR and unconfined compression tests, were also conducted.

The research findings have validated the concept of using deflection testing results to identify areas of poor in-place stability within constructed subgrades. It is recommended that pilot implementations of deflection acceptance testing be …
