background
Background
  • Maintenance of traffic issues and traffic control plans (TCP)
  • Temporal and spatial requirements impact construction
    • Temporal - time
    • Spatial - dimensions
  • Options available
problem
Problem
  • Lack of early and sufficient input of traffic and construction expertise
  • Policy directives, funding and other factors often limit alternatives
  • Solution may be sub-optimal
preferred practice
Preferred Practice
  • Prior to detailed PS&E design
  • During detailed PS&E design
consider
Consider
  • Pavement related processes
    • What is done
    • Pavement treatments and materials
consider1
Consider
  • Non-pavement related processes
    • How is pavement treatment accomplished
    • Traffic and construction related issues
process approach
Process Approach
  • Integrate pavement and non-pavement related processes
  • Process developed under NCHRP Project 10-50A
  • Fundementals
    • Start early in project development
    • Use multidisciplinary team approach
    • Analyze Traffic approaches to minimize impacts
    • Promote construction input on continuous basis
process approach1
Process Approach
  • Four main steps
    • Identify candidate sections
    • Identify pavement condition
    • Screen potential strategies
    • Evaluate feasible strategies
  • Content of steps
    • Objectives
    • Key activities
    • Issues to consider
    • Resources
    • Practical illustrations
process approach2
Process Approach
  • Validated by industry
  • Case studies demonstrated applicability
  • Documented in final report
    • A Process for Selecting Strategies for Rehabilitation of Rigid Pavements, Final Report, NCHRP Project 10-50A, February 2002

  • Description of resource
  • Relevance to analysis
  • References for more information
  • Examples
    • Work zone analysis tool - QUICKZONE

traffic and construction issues caltrans i 710 alternative
Traffic and Construction Issues:Caltrans I-710 Alternative
  • Traffic
    • Segmental full closure (3 to 5 miles) in one direction
    • All lanes available to traffic weekdays
    • Install ITS during construction
    • Recommend use of alternate routes (I-110, I-605, Lakewood Blvd. and other local streets)

Traffic and Construction Issues:Caltrans I-710 Alternative
  • Construction
    • Two concrete plants
    • Concrete plants produce about 1800 CY per hour
    • Back-up equipment and extra sources of materials
    • Recycle existing PCC pavement
    • Ten-hour shifts
    • Three stage operation
    • 16 weekends
level of analysis
Level of Analysis
  • DOT standard traffic and construction approach
  • DOT standard traffic and construction approach but with some enhanced techniques to address special issues
  • A corridor wide project-oriented traffic and construction approach

  • Traffic
  • Constructibility reviews
  • Contract methods
  • Materials and equipment

benefits
Benefits
  • Efficient and cost effective construction
  • Minimize impact on road users, local businesses
  • Safer work zones
  • Special needs identified early
application
Application
  • Most projects types and sizes
  • May have higher impact on projects with high traffic volumes
  • Concepts currently being tested
    • TRB Task Force A5T60, “Accelerating Innovation in the Highway Industry”
    • IPRF research project, “Traffic Management Studies for Reconstruction of High Volume Roadways”
application tf a5t60
Application - TF A5T60
  • Accelerated Construction Technology Team (ACTT)
    • Corridor review
    • “Outside” experts visit state experts
    • Share, learn, and promote new ideas
  • Two-day workshop with Indiana and Penn DOTs
  • Proposed use of innovation in twelve areas
  • Ultimately - DOT decides what is best for their project
application twelve areas
Corridor improvements

Contracting and procurement techniques

Work zone traffic management

Stay out techniques

Constructibility

Geotechnology

Utility delays

Prefab/modular

High speed QA/QC

Workforce health and safety

Training and education

Communications of best practices

Application - Twelve Areas
application iprf project
Application - IPRF Project
  • Task 6 Conceptual Study
  • Workshops with DOT
  • Late in programming/early in design
  • Brainstorm traffic and construction issues
  • Recommend feasible alternatives
  • Current studies
    • Mississippi DOT - I-55 South of Memphis
    • Washington DOT - I-5 through Seattle
lessons learned
Lessons Learned
  • Do not “set” design basis too early
  • Team approach enhances TCP development
  • Early involvement of traffic and construction expertise helps identify possible problems and solutions
conclusions
Conclusions
  • DOTs should be encouraged to follow concepts throughout TCP development
  • Constructibility reviews integral to TCP development
  • Team approach essential especially on larger projects
