A Review of Kansas Department of Transportation Reflective Sheeting Policy
Author: Eugene R. RussellPublisher:
ISBN:
Category : Highway engineering
Languages : en
Pages : 194
Book Description
The main objective of this study was to determine the best, cost-effective policy, consistent with safety, for sign sheeting material to be used on signs and construction work zone traffic control devices on State highways in Kansas. The investigation consisted of reviewing literature, contacting knowledgeable traffic engineers and research, conducting a survey of selected States' practice, conducting a life-cycle cost analysis, and reviewing a previous reflective sheeting study conducted for the Kansas Department of Transportation (Bellomo-McGee Inc., 1988).
Impact Assessment of Revised Retroreflectivity Requirements for Highway Signs in Montana

ISBN:
Category : Reflective materials
Languages : en
Pages : 80
Book Description
The objective of this report is to give a preliminary assessment of the impact that revised retroreflectivity requirements will have on the State of Montana. Conclusions and recommendations are made future management and handling of sign inventory data in Montana. This objective is addressed through the following tasks: Task A: Review, assimilation and analyses of current literature available on a nationwide basis; Task B: Discussion of results from a multi state phone solicitation regarding state sign management practices and policies; Task C: An assessment of sign reflectivity inspection equipment and sampling methodology; and Task D: Evaluation of Montana sign inventory on the basis of current practices and condition of a limited sampling of signs. Recommendations of this report include upgrading of, or improvements to Montana Department of Transportation sign management system and multi-district statewide retroreflective sampling to better determine the impacts revised standards may have.

Impact Assessment of Revised Retroreflectivity Requirements for the State of Montana

ISBN:
Category : Reflective materials

Pages : 86
Book Description
Traffic signing is a critical component of the roadway, as it is the communication medium by which motorists receive information relative to warnings, regulations, and guidance. Nighttime legibility is very important to the effectiveness of roadway signs. Although external sign illumination is effective, the use of retroreflective sheeting is the most common and cost effective means of making signs visible to the driver at night. This report focuses on the collection and analysis of a sample of traffic signs, delineated according to Montana Department of Transportation (MDT) District and sign type, on the State highway system. These samples were collected on the Montana highway system, focusing on non Interstate, non urban areas. These data allow cost estimates to be made for suggested sign replacements by sign category, as well as indicate appropriate and feasible replacement strategies and priorities within each MDT District and the State as a whole. Recommendations are made relative to sign management systems to easily and effectively target and document signs for future maintenance. This report details work activities associated with each of the study tasks, and concludes with findings and recommendations for Montana's course of action regarding the inventory of highway signs.
Research on Traffic Sign Retroreflective Sheeting Performance

Book Description
Sign retroreflectivity is an important characteristic of traffic signs, and it is a critical factor in defining the effectiveness of signs in a nighttime environment. This synthesis summarizes previous research on various aspects of sign sheeting retroreflectivity in nine areas: basic retroreflectivity science; retroreflectivity materials, specifications, and measurement; sign performance; sign degradation, minimum retroreflectivity; field measurement of sign retroreflectivity; economic benefits; fluorescent materials; and safety. The synthesis of previous research serves as the basis for recommendations for selecting sign sheeting based on sheeting grade and roadway environment.
