Available in PDF, EPUB and Kindle. Book excerpt: The occurrence of work zone crashes is expected to increase in Arizona with the Arizona Department of Transportation's (ADOT's) shifted emphasis from constructing new roadways to preserving existing facilities. Identifying factors that contribute to work zone crashes will lead to development of appropriate strategies to improve work zone traffic control design and management. This research effort included analysis of work zone crashes identified in the ADOT Accident Location Identification Surveillance System (ALISS) database to determine accuracy of data and to identify factors associated with work zone crashes. The research also compared information from work zone crash reports to the data in the ALISS database to identify inconsistencies. Recommendations were developed for improving the accuracy of crash investigation reporting and transcribing, and for improving work zone policies and procedures.

Available in PDF, EPUB and Kindle. Book excerpt: Nationally, work zone fatalities peaked at over 800 per year during the 1990s. Arizona tallied 82 fatal and 5,009 injury accidents in work zones during a five year period. In response to this problem, the objectives of this project included: Characterizing the nature of work zone accidents in Arizona; Reviewing countermeasures used throughout the country, and the effectiveness of those countermeasures; and Recommending countermeasures for use in Arizona to improve work zone safety and reduce accidents. A national review of work zone countermeasures was conducted, focussing on the documented effectiveness of various work zone countermeasures. To identify which countermeasures are most appropriate for use in Arizona, a panel of 21 experts was convened. The panel included representatives with a variety of perspectives on the work zone accident problem. The panel selected six principal countermeasures for implementation in Arizona: 1) Work Zone Speed Limits; 2) Police Presence; 3) Speed Limit Enforcement; 4) Public Education; 5) Sign Credibility; and 6) Temporary Pavement Markings in Work Zones.

Book Synopsis Implementing the Rule on Work Zone Safety and Mobility by : United States Department of Transportation
Download or read book Implementing the Rule on Work Zone Safety and Mobility written by United States Department of Transportation and published by CreateSpace. This book was released on 2015-02-23 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 2004, the Federal Highway Administration (FHWA) published updates to the work zone regulations at 23 CFR 630 Subpart J. The updated rule is referred to as the Work Zone Safety and Mobility Rule (Rule) and applies to all State and local governments that received Federal-aid highway funding. Transportation agencies are required to comply with the provisions of the Rule by October 12, 2007. The changes made to the regulations broaden the former rule to better address the work zone issues of today and the future. Growing congestion on many roads, and an increasing need to perform rehabilitation and reconstruction work on existing roads already carrying traffic, are some of the issues that have lead to additional, more complex challenges to maintaining work zone safety and mobility. To help address these issues, the Rule provides a decision-making framework that facilitates comprehensive consideration of the broader safety and mobility impacts of work zones across project development stages, and the adoption of additional strategies that help manage these impacts during project implementation. The Rule requires agencies to develop an agency-level work zone safety and mobility policy to support systematic consideration and management of work zone impacts across all stages of project development. Based on the policy, agencies will develop standard processes and procedures to support implementation of the policy. The third primary element of the Rule calls for the development of project-level procedures to address the work zone impacts of individual projects. To help transportation agencies understand and implement the provisions of the Rule, FHWA has been developing four guidance documents. This Guide is the main Rule Implementation Guide and provides a general overview of the Rule and overarching guidance for implementing the provisions of the Rule. This document includes guidelines and sample approaches, examples from transportation agencies using practices that relate to the Rule, and sources for more information. While this Guide covers aspects of the Rule, it also contains information that can be useful to agencies in all of their efforts to improve safety and mobility in and around work zones, and thereby support effective operations and management of our transportation system.

Book Synopsis Temporary Traffic Control for Mobile and Innovative Geometric Design Work Zones by : Timothy Cope
Download or read book Temporary Traffic Control for Mobile and Innovative Geometric Design Work Zones written by Timothy Cope and published by . This book was released on 2015 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Work zone safety and operations are of growing concern through recent years. With increasing traffic demand on the transportation system and advancing technology raising new situations, such as texting while driving and the proliferation of portable devices, new approaches and solutions need to be formed relating to transportation safety. This thesis addresses two issues pertaining to work zone safety. This first issue related to the increase of distracted driving through mobile work zones leading to an increase in collisions with work zone vehicles. Mobile work zones are continuous slow moving operations utilized for various maintenance applications such as pavement striping, sweeping, and pothole repair. This type of work zone is unique because no portion of the work zone is static and the use of and advance signage must remain mobile. The speed differential between the work zone vehicles and normal traffic flow, and the rise in distracted driving can lead to potential collisions. A possible solution to this problem involves the use of an audible warning system. This thesis evaluates two types of mobile work zone alarm systems: an Alarm Device and a Directional Audio System (DAS). Three modes of operation were tested: continuous, manual, and actuated. The evaluation consisted of sound level testing, analysis of merging distances and speeds, and observations of driving behavior. The mobile work zone alarm study found that the Alarm Device and DAS operate within national noise standards. All of the tested configurations increased vehicle merging distance except for the Alarm Actuated setup. The DAS Continuous setup reduced vehicle speeds and the standard deviation of merging distance. Some instances of undesirable driving behavior were observed for some configurations; however, it is unclear whether these behaviors were due to the use of the audible warning system. Analysis of the alarm activations showed that horizontal and vertical curves had a significant effect on false alarm and false negative rates. This research found that the use of an audible warning system has potential to be an effective tool in improving safety through mobile work zones. Further tests to the system, such as modifying the alarm sounds, could improve the warning system’s effectiveness. The second issue relates to the rising trend of utilizing innovative geometric designs to address increasing traffic and increase traffic safety. Currently there are no guidelines within the Manual on Uniform Traffic Control Devices (MUTCD) on construction phasing and maintenance of traffic (MOT) through retrofit construction projects involving innovative geometric designs. The research presented in this thesis addressed this gap in existing knowledge by investigating the state of the practice of construction phasing and MOT for several types of innovative geometric designs including the roundabout, single point urban interchange (SPUI), diverging diamond interchange (DDI), restricted-crossing left turn (RCUT), median U-turn (MUT), and displaced left turn (DLT).Goals through the innovative geometric design portion of this thesis include providing guides for transportation practitioners in developing construction phasing and MOT plans for innovative geometric designs. This involves providing MOT Phasing Diagrams to assist in traffic control measures such as barriers, delineators, and striping. Guidelines were developed for MOT through a review of literature, survey and interview of industry experts, and review of plans from innovative geometric design projects. These guidelines are provided as a tool to assist in improving work zone safety through construction of projects with innovative geometric designs. A literature review, survey of industry experts, interviews of industry experts, and analysis of project plans provided knowledge of existing practices for these types of designs. This process allowed for the development of MOT Phasing Diagrams and suggestive guidelines for each of these intersection types.
