City Council plans session on libraries By DEAN A. RADFORD dradford@rentonreporter.com

The Renton City Council will meet as the Committee of the Whole Sept. 17 for updates on the downtown library and the new library in the Renton Highlands. Renton voters by a 76 percent margin voted to keep the downtown library over the Cedar River in the Aug. 7 primary. The next step for the city is to discuss with the King County Library System how to refurbish the Cedar library. The Highlands library has been in the design phase for some time; it will anchor the Sunset Boulevard redevelopment in the Highlands. The election was certified Tuesday, with the Cedar library receiving 12,238 votes to 3,781 votes for the library site west of the Piazza. The turnout was nearly 38 percent.

New signals keep Rainier moving By ADAM McFADDEN amcfadden@rentonreporter.com

Managing traffic flow on seven-lane Rainier Avenue corridor through the middle of Renton can be tough enough on its own. Toss in construction, causing the number and positions of lanes to change, and it can be nearly impossible. Fortunately Renton brought in some help in the form of ACS Lite. By improving the efficiency of traffic lights, the new software will ease traffic for drivers through one of the most congested areas of Renton. ACS Lite, from Siemens, is an adaptive traffic-management program. The software uses video to determine “loops” in an intersection instead of the common induction loop system, where an electrically conducting loop is installed in the pavement. When

a car pulls over the loop, it changes the current in the loop and triggers the system. That is a huge bonus during the construction on Rainier, since “Even with the work crews often construction, have to modify the we are trying to number and locakeep the traffic tions of lanes. Such flowing as well as changes would likely before.” Chris Barnes, result in a frustrating city transportation mess for induction operations manager loops, but the video system can handle them in stride. The software has been perfected since 2002 and became available for purchase in 2006. Transportations operations manager Chris Barnes said it might be the first use of this software in the state.

“The adaptive traffic management system that is in place, it is where the evolution of traffic signal controls is going,” said Doug Jacobson, deputy public works administrator for transportation. “We’ve been looking for an appropriate opportunity to use it and the Rainier corridor, with things changing during construction, was that opportunity.” While the Rainier construction provides a good opportunity to showcase the video loop method, the software goes far beyond that. It also adjusts the amount of green time each movement in an intersection has to try to interactively meet the demand. For example, if 30 seconds of green isn’t clearing all the cars trying to make a left turn, the software will add green time to make the intersection flow better. Jacobson [ more signals page 6 ]
