JTRP Project "Analysis and Methods of Improvements of Safety at High-Speed Rural Intersections" was selected as a High Value Research (HVR) project by AASHTO Region 3 RAC. Purdue University Professor Andrew Tarko served as the Principal Investigator. John Nagle and Mike Holowaty of INDOT's Traffic Safety Office are among those collaborating with Professor Tarko on implementing the research recommendations that will be providing greater cost-efficient methods for INDOT to invest in traffic safety and modernizing service delivery.

The final research report explains relationships among the multiple factors in traffic safety performance at high-speed rural intersections, and recommends several specific safety countermeasures, including those that do not involve adding active signal control or carrying out wholesale reconstruction. "Recommendations of this research are already being put into practice in a variety of constructive ways," said Brad Steckler, INDOT Director of Traffic Engineering, "particularly in terms of measures to reduce risk of severe crashes by redirecting select turning movements as part of a statewide innovative intersection design initiative, addition of auxiliary acceleration lanes, and use of enhanced signing and pavement markings toward greater intersection visibility."

The results of Professor Tarko's work support the collaborative efforts with the INDOT's Research and Development division. "This is a timely example of JTRP Research Projects being aligned with INDOT Agency Goals for 2013," said Barry Partridge, INDOT Director of Research. "This recognition of Prof. Tarko's work also maps well into the Purdue Strategic Plan of Discover with Delivery," added Professor Bullock, JTRP Director.

Each of the four AASHTO regions identified 4 HVR projects and will be highlighted in an annual publication to Congress (including congressional staff members from Indiana), AASHTO Executive Members (CEO of each state), AASHTO members, TRB members, and NCHRP members. In addition to the publication, the HVR projects will be presented at the TRB/RAC meeting in Louisiana in July 2013 and highlighted at the TRB Annual Meeting in Washington, D.C. in January 2014.

2013 TRB Traffice Signal System Committee Best Paper Awards

TRB Best Paper

A paper co-authored by Christopher Day, Howell Li, Alex Hainen, Stephen Remias, and Darcy Bullock, from Purdue University along with INDOT Engineers Jim Sturdevant and Amanda Stevens received the 2013 Transportation Research Board (TRB) Traffic Signal System Committee Best Paper Award at this year's TRB conference in Washington, DC. The research paper, "Revisiting the Cycle Length--Lost Time Question with Critical Lane Analysis" documents a collaborative field study on SR 67 in Indianapolis that measured the relationship between flow rate efficiency and varying cycling lengths. The results are important to practitioners to help them select the appropriate traffic signal cycle length to provide efficient synchronization and minimize motorist delay.

Eisenhower Fellowship Recipients Meet FHWA Administrator Victor Mendez

While attending the TRB 92nd Annual Meeting in Washington, DC, Eisenhower Graduate Research Fellowship recipients Alex Hainen and Steve Remias met with FHWA Administrator Victor Mendez. Their fellowship award has provided each of them an opportunity to participate in research for adaptive traffic signal control, which is a strategic area identified by Mendez's Every Day Counts initiative. This initiative is designed to identify and deploy innovation aimed at reducing the time it takes to deliver highway projects, enhance safety, and protect the environment. Much of their adaptive control work has been related to performance measures and will be a valuable contribution to ongoing national dialog on the MAP 21 performance measures.

Additionally, they were each able to spend time with Henry Murdaugh, program manager of the Eisenhower Transportation Fellowship program of the Federal Highway Administration. Under the direction of Murdaugh, the USDOT awarded Hainen and Remias the Eisenhower Graduate Research Fellowship in February of 2012, each receiving a $34,000 fellowship for research in the area of adaptive traffic signal control. Their academic mentor, Purdue University Professor Darcy Bullock, is the director of JTRP.
