How Reliable is Your Road Network: A Comprehensive Approach to Performance Evaluation, Urban Arterial Street Safety, Operation, and Reliability

On behalf of Kittelson & Associates, Inc. in Oakland (formerly Dowling Associates) we are pleased to invite you to attend our latest Transportation Education Series (TES) workshop. These interactive workshops focus on a wide range of topics and are intended to promote professional development and advancements in transportation engineering and planning. The sessions also provide a unique forum for transportation professionals from a wide range of public agencies to share their ideas, best practices, and challenges. Participants earn credits that can be applied to continuing education requirements. We have a wonderful opportunity lined up for you on September 19th regarding travel time reliability. Details are listed below. LUNCH WILL BE PROVIDED.


In the past, traffic congestion has been communicated only in terms of simple averages. However, travel times vary greatly from day to day, and travelers remember those few bad days they suffered through unexpected delays. Travelers want travel time reliability—a consistency or dependability in travel times, as measured from day to day or across different times of day.

Travel time reliability is a measure that's becoming increasingly important to public agencies, elected officials, and most importantly the traveling public. The reliability concept is less than a decade old and continues to be explored and advanced through research programs such as the Strategic Highway Research Program 2 (SHRP2).

About the Presentation:

The session will feature Dr. James Bonneson, Dr. Richard Dowling, and Pratyush Bhatia. Dr. Bonneson’s presentation will examine the interdependence of safety and operation of urban streets. Reliability is one means by which the interdependence of safety and operation can be jointly assessed. Dr. Dowling will present his research on a methodology to assess the robustness of signal timing plans and their associated control technology for varying demands and conditions. Mr. Bhatia will present his work on the evaluation of travel time reliability for the I-680 corridor using FasTrak data. This TES workshop will start promptly at 11:30AM and will run until 1:30 PM on Wednesday, September 19th. There is no cost to attend this session and lunch will be provided. Attendees will earn 1.5 Professional Development Hours (PDH) that can be applied to continuing education requirements.

Session attendees can expect to learn about:

He is a past member, and remains an active friend, of the following TRB committees:ANB20 Safety Data, Analysis, and Evaluation, AFB10 Geometric Design, AHB4O Highway Capacity and Quality of Service, and A3A11 Traffic Flow Theory and Characteristics.

Richard G. Dowling , PH.D., P.E., Senior Principal Engineer, Kittelson & Associates, Inc.

Dr. Richard G. Dowling, P.E. is a licensed Civil and Traffic Engineer in the State of California. He has over 30 years of experience in transportation planning, traffic engineering operations, research and education as a municipal employee and as a consultant.

Dr. Dowling has been the principal investigator for several National Cooperative Highway Research Program (NCHRP) projects including: NCHRP 3-97, Traffic Signal Analysis with Varying Demands and Capacities, NCHRP 3-55(2), Planning Techniques for Estimating Speed and Level of Service, NCHRP 25-21, Predicting Short-Term and Long-Term Air Quality Effects of Traffic-Flow Improvement Projects, and NCHRP 3-70, Multimodal Level of Service for Urban Streets.

He led the development of a new chapter in the 2010 Highway Capacity Manual on Active Traffic Management.

Dr. Dowling was chairman of the Transportation Research Board committee on Highway Capacity and Quality of Service (AHB40) from 2001 to 2010. He was extensively involved in the development of the 1994, 1997, 2000 and Year 2010 Highway Capacity Manuals. He developed the TRAFFIX and CSLOS software to aid analysts in the application of the Highway Capacity Manual to traffic impact analyses and the multimodal analysis of “Complete Streets”. He also served on the Transit Cooperative Research Program (TCRP) panel of experts overseeing the update of the Transit Capacity and Quality of Service Manual 3rd Edition (TCRP A-15C).
