Operational and Safety Implications of Three Experimental Bicycle Safety Devices in Austin, Texas

摘要: Many cities in the United States are seeking ways to safely and effectively integrate bicycles into urban transportation network. To address safety issues that arise along bicycle routes Austin, Texas, this observational study examined operational implications of three new devices—Shared Lane Markings, “Bicycles May Use Full Lane” signs, colored lanes at conflict areas—to determine what improvement they offer. When existing right-of-way cannot accommodate lanes, Shared Markings signs improved bicyclists occupying full lane by encouraging ride a more central position lane, but did not always reduce unsafe bicycling behavior (like sidewalk riding or bypassing queues stopped vehicles). Motorists sites often provided greater space while passing were less likely pass bicyclists. Other concerns where crosses motor vehicle such as freeway entrance ramp motorists accessing right-turn bay must cross lane. These areas traditionally dashed, could be acquired applying yellow-green thermoplastic dashed area. utilize turn signals when crossing area all yield was guided across
