  21. 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)

  22. 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.)

  23. 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)

  24. 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

  25. 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
