2 All Work Zones MUST follow MUTCD principles! UNIFORMITY across boundaries National MUTCD or substantial conformance It is the Law (23 USC Sec. 109(d), 23 CFR ) 23 CFR (a) applicability Toll Roads Private Roads open to Public All Streets, Highways, Parking Areas It is Oklahoma State Law Part 6 Temporary Traffic Control Make it Safer!

3 MUTCD Part 6 Temporary Traffic Control Typical Applications (Part 6H) Shall / Should Restricted Conditions! Enhanced / Incorporate Smarter (ITS) devices Must be LIVE / Responsive Detect Feedback / Update Static message CMS is not SMART use of CMS

4 Smarter / Safer Work Zones begin with proper planning and design Project PLANNING! Identical Processes / Procedures for State & Local Long-Term / Short-Term Duration ADT, Queue, Staging, Phasing, Equipment Closed Lanes / Alternative Routes Special Events / Business Access Other WZ adjacent to current work zone Coordination among CMS Other modes of Transportation Incident Management Minimize Travel Disruption

5 Quality of Work Zone Traffic Control (Devices) ODOT / Contractor Work Zone Summit April 6, 2016 Norman, Oklahoma

6 TRAFFIC CONTROL DEVICE REQUIREMENTS ALL traffic control devices need to follow basic requirements to be effective: Fulfill A Need Command Attention Convey a Clear, Simple Meaning Command RESPECT of the Road User Give Adequate Time for Proper Response Five Factors that should be considered in the application of traffic control devices include: Design Placement Operation Maintenance Uniformity

7 IN GENERAL ALL temporary traffic control devices shall be: 1. In conformance with MUTCD, latest version, 2. Installed and Maintained at locations and orientations that maximize safety and minimize disruption to traffic flow, 3. Positioned as to not obstruct other applicable traffic control devices, 4. Free of appreciable dents, holes, deformations, abrasions, tears, marks, stains, residues, fading, or other deficiencies that affect the operational performance of the device. 5. Free of deficiencies that are cause for failure of the device to conform with requirements for crashworthiness. 6. Properly covered, turned, stowed, or removed when not in use.

11 SMART WORK ZONE SYSTEM A "smart work zone system" is the application of computers, communications, and sensor technology to freeway transportation and would possess the following general characteristics: Real-time Portable Automated: Reliable:

12 These systems, if properly designed and implemented, will: Better inform motorists and reduce their frustrations; Encourage motorists to take alternate routes; Reduce congestion and allow more freely flowing traffic; Clear incidents more quickly, thereby reducing secondary incidents; Make work zones safer for highway workers and motorists.

13 Intelligent Transportation System Applications Real-Time Traveler Information Queue Warning Dynamic Lane Merge Incident Management Variable Speed Limits Automated Enforcement Entering/Exiting Construction Vehicle Notification Performance Measurement

14 Travel Time A Travel time can be displayed on DMS before the work zone. Work zone sensors detect slowing traffic through the work zone. The travel time will increase to show the delay. This is meant to inform drivers of the slowdown. The driver can choose to wait or find an alternate route

15

16 Variable Speed Limit Work zone sensors detect slowing traffic through the work zone. The speed limit can vary by decreased to warn the Q of slower traffic ahead. This is meant to increase headway between vehicles to decrease collisions.

17 Multiple Project Coordination Multiple projects along a corridors can be confusing and frustrating to drivers. Over lapping signs and undefined work zones provides an unclear message to drivers Create a unified Traffic control plan for the corridor to give a concise message to drivers Give travel times through the end of all work zones to show true delay

18 Instrumented Work Zone Drums Drums can be instrumented with some of the following features for data collection and worker safety: Sensors (Location, Speed and Volume) Infrared Ultrasonic Magnetic Microwave Radar Video Audible Warning Visual Warning Communications
