Project Goals • Improve Safety of Traffic flow (Vehicular and Pedestrian) • Control Excessive Traffic Speeding • Address Traffic Congestion and Queuing problems during School peak hours • Improve Drainage and inadequate Storm Sewer system
Project Needs • Excessive Speeding along 156th Street • 171 traffic citations (2006); • 199 citations (2007); • 150 citations (2008); • 135 citations (Jan-June 2009) • Speed Records along 156th Street • for 2008 - 81 mph • for 2009 - 59 mph
Speed – Drivers Cone of Vision 40 mph 30 mph 20 mph
Project Needs Poor Traffic Operations and Queuing during school peak hours.
Project Needs Drainage – Open Ditches and existing storm sewer inadequate causing runoff and flooding.
Project Needs Roadway – 156th Street Pavement rapidly degrading. No resurfacing or rehab done in the last 15-20 years.
Project Alternatives • No-Build Alternative • Current 2-lane section along 156th St • 4-way stop at 156th St & Bennington Rd • Does not improve traffic operations, excessive speeding and queuing issues • Does not improve safety of Pedestrian/ Bicycles • Drainage problems will continue to exist
Project Alternatives • Build Alternatives • Widen 156th Street to a 3-lane roadway with a center left-turn lane • Provides additional capacity to handle future volumes and queuing at School • Provides a refuge lane for left-turning vehicles • Provides a transition area for medians and landscaping – shorter pedestrian crossings • Traffic Calming like Chicanes (curved roadway) can be effectively incorporated to slow traffic
Project Alternatives Incorporate ‘Traffic Calming’ elements to control excessive speeding Chicanes (Curved Roadway) Medians Landscaping, Trees Roundabouts etc.
Project Alternatives Build Alternatives Install a Traffic Signal at 156th St & Bennington Rd More Right-of-way needed to install exclusive left-turn lanes Volumes do not meet ‘Federal Traffic Signal Warrants’ till 2030 – No federal money can be used
Project Alternatives Build Alternatives Install a Roundabout at 156th St & Bennington Rd Excellent traffic control to reduce speeds (15-20 mph) Good pedestrian crossings – Shorter crossing distance with refuge medians (one lane at a time) ADA compliant design Eligible for federal funding Functions as a ‘Gateway’ from South
Chicanes Curved Roadways to break drivers line-of-sight and Slow drivers
Roundabouts – How they work ? Source/ Credit: Kansas Dept of Transportation
Roundabouts(similar to the proposed one in Bennington) Test Drive a Roundabout in Omaha Happy Hollow Blvd & Elmwood Park Road ( near 60th & Dodge)
Public Opinion about Roundabouts Source: Wisconsin Dept of Transportation
Project Area Stop Signs 3-Lane Section (Center turn lane + 1 NB thru lane + 1SB thru lane
Project Area Chicane
Estimated Costs • Project Total Cost - $ 3,7000,000(approx.) • 156th St/ Bennington Rd Intersection • Roundabout - $ 375,000 • Traffic Signal - $ 550,000 • Mill & Overlay Total Cost - $ 200,000(approx.) (1” mill + 2” overlay to existing roadway – no drainage improvements or traffic signals or roundabouts )
