Roundabout Leadership a Hallmark of KAI

April 16, 2014

When Ed Myers was asked to consider a roundabout for an interchange on the D.C. Beltway 25 years ago, little guidance was available at the time. In those pre-Internet days, few American cities were implementing roundabouts, so he turned to Europe and Australia for examples.

“Primarily what they were finding was there was a pretty significant safety benefit to roundabouts, with a 50 to 80 percent reduction in crashes,” said Ed, now a senior principal in Kittelson & Associates’ Baltimore office.

Arterial Prioritization Process Focuses City Funding

January 08, 2013

Historically, if the City of Bend made safety improvements to a particular area, chances were it was because a contingent of citizens came before the City Council to voice their perceived safety problems and the City would allocate funding to fix those problems. Recently, however, the City recognized that a data-driven approach would more effectively prioritize safety improvement needs and result in more cost-effective solutions to addressing them. In addition, a data-driven process would help the City become more proactive in addressing safety needs. The City worked with a consultant team to create a process that allows it to have a focused and reproducible approach to determine where to spend project dollars.

Improving System Prioritization Using Safety-Focused Decision Making

January 08, 2013

As transportation professionals and agencies have sought to better manage and optimize transportation infrastructure, the approach to performance measurement has evolved from a narrower focus on output—miles of rumble strips or number of reflectorized road signs installed, for instance—to data-driven outcome measures that quantify safety and performance. These new approaches are made possible by innovative tools that are improving transportation system management and operations amid shrinking public budgets and a drive for greater government accountability.

Leading the Way in Safety Analysis and Highway Management

January 08, 2013

More than a decade ago, Girish “Gary” Modi, PE, Chief of the Pennsylvania Department of Transportation’s (PennDOT) Safety Management Division, began analyzing system-wide data that showed a troubling trend. Several of PennDOT’s districts were experiencing higher than average head-on crashes on two-lane highways. Modi pinpointed the district locations that had a high probability of such crashes and, in 2001, sent them a letter suggesting they install centerline rumble strips to improve safety on their two-lane highways. “It was a new concept at the time and people were a little skeptical,” he admitted.

Going Green by Flashing Yellow

November 17, 2011

Use of the Flashing Yellow Arrow (FYA) at signalized intersections is a safe, low-cost approach to reducing delay and greenhouse gas emissions. The Portland office of Kittelson & Associates, Inc. hosted a recent presentation that highlighted benefits and considerations supporting the use of FYA protected-permissive left-turn (PPLT) signal control.

NCHRP Synthesis 412: Speed Reduction Techniques for Rural High-to-Low Speed Transitions was recently released by the Transportation Research Board (TRB). This synthesis is a state-of-the-practice report concerning effective and ineffective rural high-to-low speed transition treatments that have been tried by state DOTs and some overseas agencies. The scope of this research was limited to engineering measures that are used to transition motorists from high-to-low speed areas, and does not include the broader topics of speed management or the more specialized techniques and methods required for areas such as work zones, toll plazas, and school zones. The NCHRP Committee for this project was chaired by Cathy Nelson of Oregon DOT. John Mason of Auburn University was one of many other committee members also involved in this project.

Roundabout Myth #4: Roundabouts are Difficult & Unsafe for Pedestrians to Cross

May 05, 2011

Roundabouts have many benefits over stop-controlled and signalized intersections. They have proven safety benefits, often have lower delays, can lead to less traffic, can reduce the need for widening, can reduce speeds in and around the roundabout, and can provide an overall benefit to the surrounding community; however, roundabouts are often misunderstood.

This is the final post in a series that aims at tackling some of the myths related to roundabouts. This one relates to a common misperception concerning the safety of pedestrians. View the video below to debunk the myth!

Written by Nic Fleming from the New Scientist

With his jeans, white trainers and stripy top, Bob is every inch the well-dressed 6-year-old. He's standing in the middle of a hotel parking lot and, scarily, I'm driving straight at him. Instead of hitting the brakes, I put my foot down on the accelerator. With only about 10 yards to go, a row of red lights flashes across my windshield, and there's an urgent, high-pitched beeping sound. An instant later, I am jerked forward as the brakes slam on automatically and the car screeches to a halt just short of Bob's stomach.

Do We Tolerate Too Many Traffic Deaths?

June 04, 2010

In a recent New York Times online dicussion, experts share their thoughts regarding the important topic of traffic safety:

This holiday weekend marks the beginning of the summer road-trip season, and with it the attention to accident death tolls and pileups. While traffic-related deaths in the United States have decreased in recent years — even though more people are on the road driving more miles — the number still hovers around 37,000 fatalities a year. Should the nation work harder to reduce that number? What’s the one thing that could be done to reduce highway deaths?

Performance based analysis can support practical design-based project solutions

April 16, 2010

As communities across the country continue to grow, and federal funds to support our aging infrastructure continue to diminish, public agencies look for new ways to maximize investment dollars with minimal compromise. One key approach is the concept of Practical Design, which was pioneered by the Missouri and Pennsylvania DOTs. On April 15th, Brian Ray, from Kittelson & Associates, Inc. and Dr. John M. Mason, PhD, from Auburn University, co-presented a workshop that focused on how industry trends in performance based analysis can support practical design-based project solutions for planning and design projects. Brian and John provided a summary of current and emerging tools that can aid professionals in evaluating, screening, and selecting project alternative concepts.

Crash Modification Factors Clearinghouse

January 25, 2010

The Crash Modification Factors Clearinghouse (CMF) is just one of the tools and resources available to help transportation professionals make safety decisions. The Highway Safety Manual (HSM), expected to be released in the spring of 2010, will provide practitioners with the best factual information and tools to facilitate roadway design and operational decisions based on explicit consideration of their safety consequences. One of these tools is the inclusion of crash modification factors, which can be used to support an agency's roadway safety management process or as input to the safety prediction methods.

Research Helps Fuel Improvements in Road Safety

October 19, 2006

What does a safe road look like? Is a safe road one where vehicles, bicyclists, and pedestrians all share the same right-of-way without sidewalks or striped bike lanes? Are the shoulders paved or gravel? Are those shoulders 8 or 10 feet wide? Is it a divided roadway or is it undivided? How many driveways access the roadway in each mile? Are the driveways and intersecting streets controlled by traffic signals, stop signs, or roundabouts? How much do these elements affect roadway safety?
