General
Safety is a PRIMARY concernMust provide:
– safe work place– safe route for the pedestrian– safe route for the motorist
This Manual/Course cover longer term TTC that will require plans

Mn MUTCD Chapter 6B
Fundamental Principles of Temporary Traffic Control– Construction, maintenance, utility, and
incident zones can all benefit from TTC– Special plans preparation and coordination
required– Commercial vehicles might need to follow a
different route– Following the fundamental principles of Part 6
will • assist road users • help protect workers in the vicinity of TTC zones

Mn MUTCD Chapter 6B
Seven fundamental principles of TTC1. General plans or guidelines should be
developed2. Road user movement should be inhibited as
little as practical3. Motorists, bicyclists, and pedestrians should
be guided in a clear and positive manner4. Routine day and night inspections of TTC
elements should be performed5. Attention should be given to the
maintenance of roadside safety6. Training appropriate to the job7. Maintain good public relations

Why Signs are Installed
Engineering Standards– MN MUTCD
• A statement of required, mandatory, or specifically prohibitive practice regarding a traffic control device. The verb “shall” is typically used. Standards are sometimes modified by Options
• A statement of recommended, but not mandatory, practice in typical situations, with deviations allowed if engineering judgment or engineering study indicates the deviation to be appropriate. The verb “should” is typically used. Guidance statements are sometimes modified by Options

Why Signs are Installed
Engineering Standards– MN MUTCD
• A statement of practice that is a permissive condition and carries no requirement or recommendation. Options may contain allowable modifications to a Standard or Guidance. The verb “may” is typically used
• An informational statement that does not convey any degree of mandate, recommendation, authorization, prohibition, or enforceable condition. The verbs “shall”, “should”, and “may” are not used in Support statements 10

Planning for TTC
Speed Limits in Work Zones– Speed limit in work zone when workers
present• The speed limit on a road having an
established speed limit of 50 mph or greater is adjusted to 45 mph in a work zone (remember definition) when…
• At least one lane or portion of a lane of traffic is closed in either direction
• Workers are present• Exceptions follow -

– No more than 15 mph on a street or highway with an established speed limit of 50 mph or less

TMP Development
TMP Development Tips– Start early
• TMP development should start as early in the project development process as possible so that TMP strategies can be accounted for in the budgeting/scoping process
– Coordinate early• Effective TMP is one that has input from all of the
key players in the project development process • Ensure all are involved from the start of TMP
development

TMP Development
TMP Development Tips– Use templates, guidance and other tools
• Templates, guidance, and other standardized agency resources help ensure that TMPs within an agency are consistent
• These tools also simplify TMP development by helping those developing TMPs understand what is expected for agency TMPs
– Provide TMP Training• Helps ensure consistent TMPs• Also helps personnel understand why TMPs are
important• Helps gain management buy-in for TMPs, as
management support is needed for effective TMP efforts

TMP Development
TMP Development Tips– Assess, Monitor and Update the TMP
• Include funding for monitoring traffic conditions during construction to track TMP effectiveness
• Can be a challenge because it requires additional time beyond just developing the TMP
• Monitoring and updating the TMP as the project progresses or new potential impacts are discovered is important to ensuring the TMP remains effective at increasing work zone safety and mobility

TMP Development
TMP Development Tips– Document everything
• TMP becomes a written history of the project• If design and development decisions are well
documented, time, energy and money can be saved in the development of the project, as well as future projects
• A brief standardized report at the completion of major projects that describes the TMP development and implementation process and outcomes can be very beneficial to future projects

TMP Development Tips– Understand diversion rates
• Accurate estimates of diversion rates can be useful• Some people will divert to an alternate route• This reduction in demand may make a broader
range of construction and MOT options feasible, possibly reducing project or TMP cost
– Facilitate use of alterative routes• Look into the feasibility of alternate routes early in
the TMP process• If improvements are needed to alternate routes,
schedule that work at least a year prior to the project so that the alternate routes can be ready for use once the project begins
74

TMP Development Tips– Use strategies that keep lanes open
• Some examples are imposing damages for late lane opening; contract incentives/disincentives; narrowing lane widths or occasionally using shoulders during peak periods to maintain the number of lanes; night work
– Consider using extended closures vs. full closures vs. numerous night closures• Extended and full closures can greatly reduce
overall construction time and in many studies, it has been found that the public prefers one long-term closure to numerous smaller closures because the work can be completed sooner
