One-Lane Chokers <br /> <br />Description: <br />Raised islands built to narrow the roadway <br />to one lane. The one-lane choker creates a <br />short one-way section on a two-lane, two- <br />directional street, requiring vehicles to <br />yield to oncoming vehicles already in the <br />choker. The islands are detached from the <br />curb line, allowing bike lanes to continue <br />behind the choker. <br /> <br /> Application: · Streets where speed and cut-through control is desired <br /> · Typically used in mid-block locations <br /> Can be used to narrow roadway and shorten pedestrian crossings <br /> <br /> Advantages: · Pedestrian crossing distance reduced <br /> <br /> · Will reduce vehicular speed if oncoming traffic is present <br /> · Will discourage cut-through traffic <br /> <br /> · Breaks up drivers' line-of-sight <br /> <br /> Disadvantages: · May significantly reduce emergency response and ambulance transport times <br /> · Potential for increased, head-on accidents <br /> · Creates hazard for bicyclists <br /> · Creates physical obstruction in the travel way <br /> · Will require additional signs <br /> Will require removal of parking <br /> <br /> Special Considerations: · Requires special approval by the Fire Department for use on critical emergency response routes <br /> · Other impacts to emergency response should be considered <br /> · Significant problems with maintenance <br /> <br /> · Debris builds in bike lane between the choker and the curb line, creating hazard for bicyclists <br /> <br /> Cost: <br /> · Moderate <br /> <br /> <br />
