�tf <br />Architectural, landscape Architectural, <br />Engineering and Land Surveying Firms Only (CCNA) <br />® Along with recommendations for improving the facilities for all modes of travel, Kimley -Horn can explore ways to improve traffic <br />® signalization through expanded capabilities of the existing computerized traffic signal systems in the project area and the possible <br />integration of intelligent transportation system components. <br />A <br />Intersection Design <br />A roadway intersection is a critical building block in any transportation <br />infrastructure. The efficiency of intersection operation maximizes <br />the efficiency of the entire roadway system. Unfortunately, as travel <br />patterns change and grow, intersections need to be "re- tuned" to <br />provide long -term safe operation. <br />To design a new intersection or to retune an existing intersection, <br />the elements of an intersection, both individually and collectively, <br />must be understood. Every intersection has a unique combination of <br />elements— roadway layout, signal equipment, and mix and volume <br />of vehicles, pedestrians, and bicycles. As a result, every intersection <br />requires careful study prior to designing the various intersection design <br />elements to produce a safe and efficient intersection. <br />A good intersection design also allows the intersection, when signalized, to adjust timing automatically to changes in traffic <br />volumes and travel patterns. Kimley -Horn is committed to this type design and approaches this project with a "large toolbox" and a <br />clear understanding of regional and local intersection planning and design. <br />• Traffic Calming <br />® Kimley- Horn's team of roadway designers, traffic engineers, and planners knows how to design roadways that accommodate a <br />defined volume of through traffic and pedestrian/bicycle usage while serving as corridors for business and residential development. <br />® All reasonable efforts are made to restore a balance between automobiles and pedestrians. When addressing the functional and <br />® aesthetic needs of municipal road corridors, Kimley- Horn's team emphasizes a wide variety of traffic calming principles, including: <br />• Narrowed lane widths that serve to slow traffic and reduce the overall street width —while providing safer pedestrian <br />crossings. <br />• Heavily landscaped medians that reduce the appearance of expansive paving, help slow traffic, lower the number of <br />accidents, and promote pedestrian safety through the provision of median "refuges" at crosswalk locations. <br />• Raised intersections (or `speed tables ") equal to the elevation of the sidewalk, that redefine the road as a "pedestrian area <br />through which traffic must pass" vs. traditional intersections that are clearly `vehicular spaces through which pedestrians <br />and bicyclists must pass." Such intersection designs often incorporate special paving designs to further reinforce their <br />presence and importance. <br />• Paving designs, including the use of pre -cast paving <br />systems or color asphaltic pavement mixes, help to - <br />'announce' intersections or neighborhood gateways, <br />and they provide a unique character and quality to the <br />® <br />roadway corridor. Kimley -Horn has also used special <br />pavement striping patterns to create special areas, <br />® <br />thereby reducing vehicle speeds. <br />® <br />• Traffic circles (or "roundabouts") that permit the <br />® <br />development of major gateway features, calm through <br />traffic and, in some instances, even improve the flow of <br />® <br />traffic. <br />® OY2-i00 M4.
