About SHRP 2 L11 Travel Time Reliability Research

1. Evaluating Alternative Operations Strategies to Improve Travel Time Reliability Key SHRP2 L11 Deliverables SHRP 2 L11 Team 2) Effectiveness of Transportation Agencies 5) Trends that Affect Reliability Project Outcomes: 1) Generate profile of highway users & their need for travel time reliability. Draft Completed 2) Assess the effectiveness of transportation agencies in meeting reliability needs. Draft Completed 3) Develop goals & desired performance targets for travel time reliability. 4) Develop methods for estimating the value of travel time. 5) Identify trends likely to affect travel time reliability. 6) Develop three alternative scenarios for 2030, including an assessment of their impact on travel time reliability as well as its importance to users and operators. 7) Evaluate strategies for affecting travel time reliability. 8) Develop Concept of Operations for the present as well as for three alternative futures. Identify a comprehensive set of trends regarding internal and external macro-level factors that affect travel time reliability in the present and the future.

Schofer Northwestern University Dr. Michael Myer Georgia Institute of Technology Danica Rhoades Write Rhetoric Evaluate the current effectiveness of transportation agencies, incident responders, and other stakeholders in meeting user (passenger & freight) requirements. • Identify comprehensive set of trends (internal and external) • Screen potential trends and assess their relationship to non-recurring congestion and reliability • Develop Working Paper User Requirements Urban Sprawl or Densification Privatization Energy Costs Technology • Strategies Implementable by Agencies. • Ability of Agencies to Implement Strategies under current , resource-constrained conditions. • Qualitative Measurements to Rank Effectiveness of • Strategies. Assess how these trends are influenced by factors internal and external to the Transportation Agency Add Logos 6) Three Alternative Futures for 2030 • Identify apparent and potential trends that may: • Influence the transportation system & demands for it; • Frequency of non-recurring congestion; • Priorities placed on mitigation such congestion; • Technologies that may facilitate effective responses; • Broader social, environmental, and political context within • which future transportation system will be managed. 3) Goals for Improving Reliability Assess Reliability for 1) the Network as well as 2) entire Transportation System. 1) Current & Future User Needs The objectives of this task are to classify users into groups and identify measures of travel-time reliability for each group. About SHRP 2 L11 Travel Time Reliability Research Passengers Changes & Enhancements in Supporting Technologies Global Climate Change SHRP2 Program: SHRP2 is a targeted, short-term research program aimed at addressing the challenges of moving people and goods efficiently and safely. Within the overarching aims of the SHRP2 program, the Reliability Focus Area aims to develop approaches, methods, and practices for improving the reliability of our transportation system by reducing the adverse consequences of nonrecurring congestion. Three Alternative Futures for 2030 Purpose: Routine & Temporally Constrained Mode: Single/Double Occupant, Transit, Multi-Modal Spatial: Urban/Rural, Distance, Facilities Temporal: Time of Day, Possibility of Adverse Weather Age Children at Home Increasing & Aging Population Increases in Energy Costs Income Work Flexibility 7) Strategies and Tactics List and discuss no-, low-, and high-tech strategies and tactics that can improve travel time reliability for the following: Employment Gender • those currently in use in the U.S. and other countries; • emerging strategies and tactics; • new and innovative strategies and tactics that could appear by the more distant future, 2030. Education • SHRP2 L11 Study Objectives: • To identify and evaluate strategies and tactics to satisfy the travel time reliability requirements of users of the roadway network – those engaged in both freight and person transport in urban and rural areas. User Surveys & Discussions 4) Economic Benefits Freight Movers Develop & carry out an approach for imputing the dollar value of incremental improvements in travel time reliability to enable evaluation of alternative operations strategies aimed at reducing non-recurring congestion. 8) Operations Concept for Present and Future Sources of Congestion Develop a Baseline Concept of Operations (Con Ops) for the present. Also, develop three distinct Concepts of Operations framed by different futures for the year 2030.
