NCHRP Synthesis 412 Report Released

June 30, 2011

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.

Lord Mayor’s Award for Excellence - Brisbane, Australia

June 29, 2011

The Brisbane City Council Transport Group and Capacity Management Teams has recently been awarded the Lord Mayor’s Award for Excellence for Value for Money. This was to acknowledge the accomplishments of the team for their efforts on the Single ITS project, which was supported by Miranda Blogg of Kittelson and Associates. The following is a brief description of the award as outlined by the Brisbane City Council:

The Lord Mayor’s Helen Taylor Award for Local History provides funding to individuals to support them in the productions of work that furthers the understanding of Brisbane’s history or heritage. The award honours the work of local historian Helen Taylor, who combined her skills in researching & writing history with a passion for making history accessible to the community. In Helen’s memory, this award encourages both excellence in research & innovation in popularizing the results.”

Brisbane City and Department of Main Roads chose 12 major Brisbane City corridors for signal optimisation during all hours of the day, and included weekday and weekend plans. Kittelson’s role was to provide technical support for Brisbane City Council's Signal Retiming program using the Transyt 7F software system. The goal of the Single ITS project is to link the signal systems of Brisbane City Council, Transport, and Main Roads so they can communicate and operate in a more orchestrated and efficient manner. This will help reduce delays, fuel consumption, and emissions without physical improvements. Congratulations to BCC and Miranda!
