As a result, every intersection requires careful study prior to designing • the various intersection design elements to produce a safe and efficient intersection. • A good intersection design also allows the intersection, when signalized, to adjust timing automatically to • changes in traffic volumes and travel patterns. Kimley-Horn is committed to this type design and approaches this • project with a "large toolbox" and a clear understanding of regional and local intersection planning and design. ® Traffic Calming ® Kimley-Horn's team of roadway designers, traffic engineers, and planners knows how to design roadways that accommodate a defined volume of through traffic and pedestrian/bicycle usage while serving as corridors I• for business and residential development. All reasonable efforts are made to restore a balance between • automobiles and pedestrians. When addressing the functional and aesthetic needs of municipal road • corridors, Kimley-Horn's team emphasizes a wide variety of traffic calming principles, including: • Narrowed lane widths that serve to slow traffic • and reduce the overall street width—while • providing safer pedestrian crossings. �=.s_ ,,, J • ■ Heavily landscaped medians that reduce the � appearance of expansive paving, help slow traffic, �� ' • lower the number of accidents, and promote = r l• pedestrian safety through the provision of median „ ' '� ,�� • "refuges" at crosswalk locations. „zip 1 '_ • Raised intersections (or "seed tables") equal '` '// 1\ • to the elevation of the sidewalk, that redefine the ,rte�'u ;" ,° ;+ • road as a "pedestrian area through which traffic u ' • • AS RFO No.12-04-02 r�n Kimley-Horn 0Y300014 12o Sunny Isles E Services.indd and Associates,Inc. 0 2-2
