18 Work Zone Management

19 Final Rule Work Zone Safety and Mobility Rule Implementation of Updates to 23 CFR Section 630, Subpart J

20 Overview of the Updated Rule Establishes requirements and provides guidance for: - Systematically addressing WZ safety and mobility impacts. - Developing strategies to help manage these impacts. On all Federal-aid aid Highway Projects

21 Has affects on - Safety - Mobility - Constructability Why TMPs? TMPs = more comprehensive approach to managing WZ impacts

22 TMP Contents Transportation Management Plans (TMP) Required on all projects Temporary Traffic Control Plan (TTCP) Transportation Operations Plan (TOP) Public Information Plan (PIP) Significant Project TTCP, TOP and PIP Required Non-Significant Project TTCP Required TOP and PIP Recommended

23 NJDOT Response Policy No. 815 Work Zone Safety and Mobility

24 TMP during Planning TMP development begins in the project planning and scoping phase Involves planning and design staff Incorporates big picture issues Further details as project progresses Allows more accurate programming and budgets

25 New Jersey Department of Transportation Traffic Mitigation Guidelines

26 New Jersey Department of Transportation Traffic Mitigation Guidelines Section 1 Introduction 1.1 Purpose and Benefits of Traffic Mitigation Actions The Department is committed to providing a network of transportation facilities that enables New Jersey residents, workers, and visitors to move efficiently within and through the State. Developing and maintaining a Statewide transportation network requires that the Department periodically upgrade and improve these facilities through construction projects. The Department s first priority is to complete these projects in a timely and cost-efficient manner. The Department recognizes, however, that construction projects inconvenience motorists traveling through the construction corridors and disrupt businesses located nearby, in some cases resulting in substantial user costs.

27 New Jersey Department of Transportation Traffic Mitigation Guidelines Low impact projects - traffic demands is < work zone capacities during any time of the 24 hour day. Moderate impact projects - traffic demands is > than work zone capacities for a period of 0-6 hrs per 24 hour day. High impact projects - traffic demands is > work zone capacities for 6+ hours per 24 hour day.

28 Low impact projects The TM needs for low impact projects generally can be adequately addressed by minimal and standard traffic controls used routinely in construction areas. These could include, for example: Fixed signs to alert motorists to the presence of construction activity ahead. Traffic cones and temporary barriers to guide motorists through the construction area.

29 Moderate impact projects Augment TM strategies used in low impact projects with strategies such as- Construction area screening, Construction area screening, Variable Message Signs, Reduced Travel Speeds Temporary Parking and Turn Restrictions Pavement Markings. Detours without additional upgrades to alternate routes. Modest TDM strategies such as rideshare marketing.

30 Moderate impact projects Modest public outreach targeted to residents, businesses, and community centers in the local area affected by the construction: for example, postings on web sites, and fax network for employers and others. Construction activity restrictions/nonconstruction increases in capacity (e.g., narrow lanes) to minimize peak period delays. Development of incident management plan to reduce delays caused by accidents.

31 High impact projects Most aggressive TM strategies. More costly strategies could be appropriate due to the high cumulative cost of delay and disruption. Temporary capital improvements might be warranted to maintain capacity. Deliver information to the public-at-large and to motorists traveling through the construction area, and to support the needs of businesses for employees and customer access.

32 High impact projects Advanced traffic operations and control strategies, such as ramp metering, signal adjustments, reversible lanes, lane closure restrictions, and truck restrictions. Extensive public outreach to the public-at-large and to targeted groups, including public information meetings, brochures, news releases, media advertising, appearances at community events, a public information center, and a telephone hotline. Detours that require capital improvements to alternate routes.

33 High impact projects Temporary capital improvements, such as crossovers, temporary roadways, and temporary use of shoulders and median areas to maintain capacity. Contracting strategies, such as A+B bidding, contractor incentive/disincentive provisions, lane rental provisions, and project consolidation. Expanded TDM strategies such as temporary transit service, free bus service, Park & Ride lots, TDM information, and assistance to employers.
