"This report is intended to serve as the Participant Handbook containing the course material for the FHWA-sponsored training course of the Design and Operation of Work Zone Traffic Control. The intent of the course is to teach the proper application of the principles of Part 6 of the Manual on Uniform Traffic Control Devices (MUTCD). The course materials include design elements showing the proper design and layout of work zones under varying traffic and roadway conditions. Sample problems are presented to allow the participants of the course to apply the design guidelines to specific situations. Also included in the material are forms and procedures for inspecting and monitoring the safety and operation of work zones."--Technical report documentation p.

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.

Oregon Department of Transportation contractors are required to implement Traffic Control Plans (TCPs) to protect and direct traffic through work zones. The design and implementation of TCPs have shown variation from project-to-project across the State. The impact of this lack of consistency is magnified as a result of an increase in the number of work zones, higher traffic volumes, more work being conducted at night to minimize traffic interruptions, a greater number of parties (consultants) involved, and the pressure to complete projects faster. The primary purpose of this research study was to enable improved safety performance through work zones on state roadways. To fulfill this goal, the research aimed to identify ways to modify TCPs to improve their quality and consistency and develop suggested guidelines to follow to design, review, implement, and inspect TCPs. Implementation of the research results is expected to improve consistency of TCPs and decrease the number of work zone fatalities and injuries. Auxiliary benefits resulting from improvements in traffic flow through work zones and the elimination of work zone crashes will include greater mobility, smoother operations, and increased efficiency across the State's roadway network.
