Primary Functions of Temporary Traffic Controls z

z

Provide Safe and Efficient Movement of Vehicles, Bicyclists and Pedestrians Through or Around Bicyclists, Temporary Traffic Control Zones Provide Safety for the Workers Performing the Many Varied Tasks Within the Work Space Consideration for Road User Safety, Worker Safety, and the Efficiency of Road User Flow is an Integral Element of Every Traffic Control Zone – From Planning through Completion

The Temporary y Traffic Control Plan z

No O N One S Set off T Temporary T Traffic ffi Control C l Devices Can Satisfy All Conditions for a Given Project z Temporary Traffic Control Selected Depends On: – – – – –

Type of Highway Road User Conditions Duration of Operation Physical Constraints Proximity of Work Zone to Road Users

The Temporary Traffic Control Plan z

Detail Appropriate to Complexity of the Project j z Prepared and Understood by All Responsible Parties – Before Starting! z Any Changes Should be Approved by an Official Knowledgeable (Trained and/or Certified) in Proper Temporary Traffic Control Practices

Other Key y Elements z

z z

z

Temporary Traffic Control Devices Inconsistent with the Intended Travel Path Should be Removed or Covered Flagging Procedures Should Provide Positive Guidance to the Road Users Devices Should be Carefully Monitored Under Varying Conditions Including: – Road User Volumes – Light i h / Visibility i ibili Conditions C di i – Weather Conditions All Devices D i Should Sh ld be b Removed R d When Wh No N Longer L Needed or Work is Suspended

Other Key Elements z

Coordinate Adjacent or Overlapping Projects to Avoid Duplicative and/or Redundant Signage z Spend the Time on Public Relations – – – –

Nature of the Work Time and Duration Anticipated Effects Alternate l Routes

Follow the Plan! z 5-P’s

Temporary p y Traffic Control Zones z Advance Warning g – What to expect

Area

z Transition Area – Physically Moves the Traffic z Activity A ti it Area A or Work W k Zone Z – Includes the Buffer Space z Termination Area – “End Road Work”

Detours and TwoTwo-Way Traffic z

Detours and Diversions – Clearly Signed Over Entire Length for Ease of

Use – Put Yourself in the Motorists Shoes z

One Lane, Two-Way Traffic Control – Movement from Each End Must be

Coordinated, i.e. Flaggers, Flag Transfer, or Pilot Car

Pedestrian Safety z

Need Clearly Delineated and Usable Travel Path z Three Considerations in Planning – Should Not be Lead Into Conflicts with the

Work Zone – Should Not be Lead Into Conflicts with V hi l Vehicles – Provide Safe, Convenient Path Similar to the Existing Sidewalks or Footpaths

Worker Safety z

Equally Important as the Safety of the Road Users z Key Elements to Improve Worker Safety – Training – Worker Clothing – Traffic Barriers – Speed Reduction

Qualifications for Flaggers z

Because They are Responsible for Road User Safety and Make Frequent Contact With the Public, Flaggers Should Have: – Sense of Responsibility – Adequate Training – Average Intelligence – Physically Ph i ll Fit andd Mentally M t ll Alert Al t – Courteous But Firm – Neat Appearance
