Important issues in highway design

Important Issues in Highway Design

  • Automobile Oriented Society

    • More cars than drivers (BTS Survey 03)

  • Shift from construction of new facilities to maintenance of existing facilities (e.g., lane widening, paving, intelligent transportation systems, etc.)

  • Resurgence in highway funding

    • Concern for conditions of infrastructure

    • Renewed public willingness for public expenditures (e.g., recent bill in Texas to increase funding for highways)

    • Reauthorization of transportation funds ($286.5B)

    • 2012 Bill signed on July 6th (http://banking.senate.gov/public/_files/Transit_Bill_Summary_and_Funding_Chart.pdf)


Important issues in highway design1

Important Issues in Highway Design

  • Fleet of vehicles

    • Larger trucks/smaller vehicles

    • Better vehicles performance and design (e.g., lower center of gravity, improved acceleration, lighter vehicle components, etc.)

  • Age of population

    • Baby boomers are getting older (20% 65+ in 2003)

    • Safety issues with older (i.e., visual search, reaction time, more fragile health, etc.)


Important issues in highway design2

Important Issues in Highway Design

  • Value Engineering

    • New area that aims to find ways to save money in design

    • Has been applied in highway design

    • Can compromise safety (e.g., Highway 407 in Ontario, Canada)

  • Liability

    • Increasing number of lawsuits (DOTs, Cities, MPOs, etc.)

    • Usually always based on (un)safety (after crashes occur)


Important issues in design

Important Issues in Design

  • Safety Audits

    • Becoming increasingly popular (liability is a factor)

    • Explicitly look at all safety components of a project (from initial concept to construction)

    • Goes beyond design guidelines

    • Partial truth: good design may avoid many problems

  • New design criteria under development

    • Less focused on vehicle speed

    • Sensitive context design

  • Transportation Security

    • Terrorist threats against transportation infrastructures

    • See, e.g., http://onlinepubs.trb.org/Onlinepubs/dva/SecurityActivities.pdf


Important issues in design1

Important Issues in Design

  • Strategic Research

    • Operational effects

    • Safety effects

    • Design tools

    • Non-motorized vehicles or users (pedestrians, bicyclists)

    • Unusual design (large intersections)

    • Innovative design (pedestrian crosswalks)

    • Technology (influences the design process)

    • Low volume roads

    • Environmental impacts

    • Toll and HOV lanes
