Non-compliance with these requirements after October 12, 2007, may result in losing federal aid on existing projects and being non-eligible for federal aid on future highway projects after that date.

616.14.4 Policy-Related Guidelines

MoDOT’s Business Plan establishes safety as the top strategic issue for the department. This applies to both the individual working within the highway right of way as well as the one operating a motor vehicle affected by such work. To provide for the well-being of both the worker and the motorist in these temporary traffic control situations, minimum expectations have been established in the following documents.

EPG 616 Temporary Traffic Control outlines procedures for the preparation of traffic control plans and provides guidance on the procedures and methods that are acceptable for implementation of those plans. EPG 616 supplements the Manual on Uniform Traffic Control Devices, (MUTCD), and Sec 616 by providing personnel with a convenient guide for the policies, procedures and methods presently acceptable in the development and inspection of traffic control plans for highway construction.

EPG 616.23 Traffic Control for Field Operations (TCFO) contains information on the proper deployment of temporary traffic control measures on the state highway system and is based upon Part 6 of the MUTCD, as well as MoDOT policies and best practices. TCFO is applicable to incident management, maintenance, permit and utility operations performed on MoDOT right of way. A maintenance operation is considered any field operation performed by a MoDOT employee. TCFO is divided into two major parts. The first part contains basic temporary traffic control guidelines used on the state highway system. These guidelines provide insight into the development of the typical applications and may be used by supervisors to develop a temporary traffic control plan for a particular situation not covered by one of the typical applications. The second part contains the most common temporary traffic control plans needed for work accomplished within the highway right of way. These typical applications feature information on and a schematic of how the temporary traffic control zone is to be set up.

The Permit Guidelines includes guidance to permittees on their responsibilities in performing their work on state highway right of way. The guidelines require permit operations to report their lane closures to MoDOT, to have a copy of the executed permit on-site whenever work is occurring, to have a copy of the applicable temporary traffic control plans or manuals on-site when lane drops are present, to use traffic control devices that are MUTCD compliant, to have personnel trained in performing their specific temporary traffic control duties, and to have one representative on-site for ensuring that all temporary traffic control measures are properly installed and maintained according to the temporary traffic control plan. This representative shall also be able to read and understand temporary traffic control plans; shall be knowledgeable of the requirements set forth in Part 6 of the MUTCD; and shall be able to apply those concepts under dynamic field conditions.

Quality Standards for Temporary Traffic Control Devices contains quality standards that are applicable to all temporary traffic control devices (e.g., impact attenuators, truck mounted attenuators, signs, channelizers, barricades, warning lights, changeable message signs, flashing arrow panels, work zone traffic signals, lighting units, temporary pavement marking, temporary traffic barrier, etc.). The standards comply with MUTCD Section 1A-05. The quality standards set forth are to be used by those responsible for the installation, operation, maintenance and inspection of temporary traffic control devices as a guide to determine if those devices are acceptable for use on the state highway system.

EPG 910.3 Dynamic Message Signs (DMS) and EPG 616.6.60 Portable Changeable Message Signs provide specific guidelines for the use of all stationary dynamic message signs (DMS) and portable changeable message signs (CMS) used on the state highway system.

616.14.5 Tracking Measures

MoDOT will publicly report its ability to provide safe, effective and efficient work zones on state highways via three Tracker measurements on a quarterly basis. These measures (percent of work zones meeting expectations for traffic flow, percent of work zones meeting expectations for visibility and number of fatalities and injuries in work zones) relate to MoDOT’s tangible results of uninterrupted traffic flow, roadway visibility and safe transportation system, respectively.

616.14.6 Training

All MoDOT personnel, contractors, law enforcement, and permittees will be trained in temporary traffic control design, deployment, operation, enforcement and maintenance commensurate with their level of responsibility. Individuals may gain this training through either department-provided courses or outside sources. MoDOT currently provides training on flagging, TMA operation, and basic and advanced technical principles pertaining to design, setup, maintenance, management and evaluation of work zones. Training will be updated to reflect changes in MoDOT philosophy and application. For training opportunities, individuals or companies may contact Traffic or Human Resources Employee Development. Available MoDOT training modules are:

• Advanced Work Zone Training
• Flagger Training
• Truck- and Trailer-Mounted Attenuators
• Work Zone Technician Training
• Work Zone User Manual, Web Version

616.14.7 Process Review

The quality assurance inspections of work zones conducted on a daily basis by Central Office and district staffs cover 23 specific items pertaining to the visibility of work zones and 10 specific items pertaining to traffic flow through work zones. Traffic will review quarterly the ratings of these 33 items to determine where MoDOT is managing work zones well and where improvement is needed. Based on those results, Traffic will develop new or refine existing work zone guidelines/policies/standards or provide that information to the Work Zone Quality Circle for review.

The Work Zone Quality Circle will review statewide work zone trends and evaluate new work zone safety devices, methods and guidelines. Based on those reviews and evaluations, the Work Zone Quality Circle will make recommendations for improving the safety and mobility of work zones on MoDOT’s right of way.

The Work Zone Review Team will conduct audits of work zones in three different districts each year. These audits will consist of very detailed inspections, covering the technical aspects of work zones in regards to managing visibility and mobility. The audits in each district will last approximately a week and cover all active work zones in that district. At the end of each audit, the Work Zone Review Team will share their findings with the district staff. Then upon completion of all of the audits for a given year, the results will be shared statewide to assist districts in assessing and managing their respective work zones. The findings will be provided to the Work Zone Quality Circle to take appropriate corrective action.

A Work Zone Summit will be held annually to provide an overview of action taken in the past year and to discuss direction and initiatives for the upcoming year for work zones and related safety issues. The overview will, at minimum, cover the following items: new legislation laws and initiatives; MoDOT policy revisions and considerations, Tracker issues pertaining to work zones; new work zone innovations; specification changes; and new products. Representatives from each district and Central Office division are encouraged to attend.

616.14.8 Significant Projects

A significant project is one that, alone or in combination with other concurrent projects nearby, is anticipated to cause sustained work zone impacts greater than what is considered tolerable based on this policy and/or engineering judgment. Work zone impacts refer to work zone-induced deviations from the normal range of transportation system safety and mobility. The extent of the work zone impacts may vary based on factors such as, road classification, area type (urban, suburban and rural), traffic and travel characteristics, type of work being performed, time of day/night, and complexity of the project. These impacts may extend beyond the physical location of the work zone itself and may occur on the roadway on which the work is being performed, as well as other highway corridors or other modes of transportation.

During the initial planning and development stages for projects on the Statewide Transportation Improvement Program, projects will be considered significant by meeting one or more of the following criteria:

1. It is an interstate project occupying a location for more than 3 days with either intermittent or continuous lane closures.

2. The project is on a Major Route in an urban area.

3. The project will cause capacity values to exceed those in the Work Zone Guidelines. Refer to Roadway Capacities.

- Typically, mobile operations will not be significant projects.

- Typically, if state route traffic is not affected during construction the project will not be significant.

During the delivery and development process, the transportation management strategy matrix should be used to assist planners, designers and field operation and construction personnel in developing a Transportation Management Plan (TMP). Another that should be used at the core team meetings is the Work Zone Questions for the Core Team.

Exceptions to significant project status may be requested to FHWA. Exceptions may be granted by FHWA based on MoDOT’s ability to show the specific project does not have sustained work zone impacts.

616.14.9 Assessment of Work Zone Impacts

A transportation management strategy matrix has been developed by MoDOT to assist planners, designers, permit staff and field personnel (e.g., maintenance forces, resident engineers, contractors, permittees) in choosing strategies to help with the safe and efficient movement of traffic in work zones. The traffic management strategy matrix consists of key questions to ask and identifies corresponding strategies to manage the work zone impacts of a project. The traffic management strategy matrix is a tool that should be used throughout all phases of a project, from the preliminary development stage to final construction of a project.

Some other tools that can be used alone or in combination to assess work zones impacts are located in EPG 616.13 Work Zone Capacity, Queue and Travel Delay. Another that should be used at the core team meetings is the Work Zone Questions for the Core Team.

Additional information is available via the Work Zone & Traffic Analysis/Management section of the FHWA Work Zone website. In addition, Work Zone Impacts Assessment: An Approach to Assess and Manage Work Zone Safety and Mobility Impacts of Road Projects provides an overview of many of these work zone impacts analysis tools.

616.14.10 Work Zone Transportation Management Plan

The Transportation Management Plan (TMP) consists of strategies to manage the work zone impacts of a project. For non-significant projects, the TMP may consist of only a Traffic Control Plan (TCP) and any necessary Job Special Provisions (JSP). For projects that have been determined to have a significant impact (see EPG 616.14.8 Significant Projects) on roadway users to include, the TMP must include a TCP, JSPs, and an Executive Summary document that includes, at a minimum, a Transportation Operations (TO) component and a Public Information (PI) component. For additional information, see EPG 909 Transportation Systems Management and Operations for the Work Zone Management Guidebook and associated presentation.

A TCP shows the design and layout of the temporary traffic control measures to be used for facilitating road users through a work zone. The TCP should be consistent with MoDOT policies, guidelines and standards, and at minimum shall meet the provisions of Part 6 of the Manual on Uniform Traffic Control Devices (MUTCD) and the work zone recommendations in Chapter 9 of the AASHTO Roadside Design Guide. The TCP will maintain pre-existing roadside safety hardware at an equivalent or better level of condition than existed prior to project implementation.

TMP Examples

Rte. 50 Lafayette Interchange

Rte. 54 Missouri River Bridge

Rte. 79 Bridge K-487 over Noix Creek

In addition to the TCP, the necessary JSPs should be included to ensure the work zone operates as desired and so the contractor is aware of all contractual obligations in regards to work zone management. A variety of JSPs may be appropriate for the project including, but not limited to, Work Zone Traffic Management, Emergency Provisions and Incident Management, Zipper Merge, Work Zone Intelligent Transportation Systems (WZITS), and Law Enforcement.

When a project is determined to be significant, the TO and PI components of the TMP should be addressed in the Executive Summary document. The TO component of the TMP shall include the identification of strategies that will be used to mitigate impacts of the work zone on the operation and management of the transportation system within the work zone impact area. The TO component should also include an incident management plan for the work zone impact area. The scope of the TO component should be determined by project characteristics and consist of the strategies derived through use of the Work Zone Questions for the Core Team or the transportation management plan strategy matrix. Strategies and responsibilities identified in the TO component to be performed by the contractor should be incorporated into the TCP or JSPs.

The PI component of the TMP shall include communication strategies that seek to inform affected road users, the general public, area residences and businesses, and appropriate public and transportation entities about the project, the expected work zone impacts and the changing conditions on the project. This may include real-time traveler information strategies such as changeable message signs, websites, and social media updates. The scope of the PI component should be determined by the project characteristics and the public information and outreach strategies identified through the use of the Work Zone Questions for the Core Team or the transportation management plan strategy matrix. Public information should be provided through methods best suited for the project and may include, but not limited to, information on the project characteristics, expected impacts, closure details, and commuter alternatives. Strategies and responsibilities identified in the PI component to be performed by the contractor should be incorporated into the TCP or JSPs.

The TMP should be developed and implemented in sustained consultation with all stakeholders (e.g., other transportation agencies, railroad agencies/operators, transit providers, freight movers, utility suppliers, police, fire, emergency medical services, schools, business communities, and regional transportation management centers).

The plans, specifications and estimates for the project shall include the entire TMP (if a significant project), including the Executive Summary, the TCP, JSPs, and appropriate pay item provisions for implementing the TMP, by individual pay items, lump sum payment or a combination of the two. In addition, the Executive Summary should be submitted as part of the electronic deliverables for the project.

The TMP, including the Executive Summary, should also be a point of discussion with the contractor at the project pre-construction meeting.

MoDOT's Traveler Information Map

616.14.11 General Public Information

In addition to the work zone-specific Public Information activities, MoDOT provides general work zone information to the public through various outlets. These include, among other things, publication of a statewide work zone map and work zone driving safety tips, posting of current work zone locations and conditions to the internet, promotion of Work Zone Safety Awareness Week, and advertisement of work zone safety-related messages via radio, television and, billboards. Through these efforts, MoDOT positively influences work zone safety and mobility, as motorists gain access to information they need to plan their trips and become more work zone conscious.
