Object Markers at Narrow Bridges on Low Volume Rural Roadways


Book Description

Kansas State University conducted a study to identify and evaluate potential alternatives for marking narrow bridges. Based on the results of the literature review, the surveys of current practices and the field observations, several alternative signing strategies for low volume bridges were formulated. These alternatives include: 1) do not use object markers on low volume roadways, 2) reduce the height of object markers on low volume roadways, 3) stagger the object markers on low volume roadways, 4) use flexible sign supports, 5) use removable object markers, and 6) redesign the object marker and/or support. Implementation of such practices statewide could result in substantial cost savings to the highway agencies.










Handbook of Traffic Control Practices for Low Volume Rural Roads


Book Description

The main purpose of this Low Volume Rural Road (LVR) Handbook is to assist the local government officials in providing traffic control and guidance for persons driving on LVR. The suggested practices in the LVR Handbook are in accordance with the Manual on Uniform Traffic Control Devices, 2003 Edition (MUTCD 2003)and, in some cases, address more specifically the application of MUTCD 2003 to LVR. This handbook also includes background information on the characteristics of LVR.




Gravel Roads


Book Description

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.







Positive Guidance in Traffic Control


Book Description

The progress that has been made in developing the positive guidance concept is documented, and the meaning of positive guidance, the philosophy of driver performance upon which it is based the nature of the driving task at those locations where positive guidance is applicable, and a procedure for its application are discussed. This report describes what must be done to improve the information system at hazardous locations. Positive guidance which is an information system matched to the facility characteristics and driver attributes, is based on the premise that a driver can be given sufficient information where he needs it and in the form that he can best use to avoid hazards.




Low-Volume Roads Engineering - Best Management Practices Field Guide


Book Description

This Low-Volume Roads Engineering Best Management Practices Field Guide is intended to provide an overview of the key planning, location, design, construction, and maintenance aspects of roads that can cause adverse environmental impacts and to list key ways to prevent those impacts. Best Management Practices are general techniques or design practices that, when applied and adapted to fit site-specific conditions, will prevent or reduce pollution and maintain water quality. BMPs for roads have been developed by many agencies since roads often have a major adverse impact on water quality, and most of those impacts are preventable with good engineering and management practices. Roads that are not well planned or located, not properly designed or constructed, not well maintained, or not made with durable materials often have negative effects on water quality and the environment.
