Tucson is a pioneer in the develop- ment of bicyclist- and pedestrian-ac- tivated signals. The first signal was installed in 1998 along Third Street to help bicyclists and pedestrians cross Country Club Road. Fortunate- ly around that time City of Tucson Traffic Engineer Dr. Richard Nassi observed a unique pedestrian cross- ing while he was on vacation in En- gland. Dr. Nassi modified the design to meet U.S. engineering standards and the HAWK High-intensity Acti- vated Crosswalk was born Dr. Nassi continued to experiment and innovate with crossing treat- ments to fit the needs of various roadways. His avian-themed pedes- trian crossings - the TOUCAN which stands for TwO groUps CAN cross and HAWK are essentially bicyclist- and pedestrian-activated signals that help people traveling on minor streets cross major roadways more safely and comfortably. There are more than 115 HAWK signals around Tucson today. And now after being approved for use in the Manual on Uniform Traffic Control Devices the national traffic control manual published by the fed- eral government these signals are popping up all over the country. These signals do ex- actly what Dr. Nassi and the City of Tuc- son hoped they would Studies show that mo- torists yield to pedes- trians using HAWK beacon signals 97 of the time according to a soon-to-be re- leased Federal Highway Administra- tion FHWA 2016 report. Pedestrians on average use the crossing beacon 91 of the time. Another previous study conducted in 2010 showed that intersections had a 69 average de- crease in crashes involving pedestri- ans after the installation of a HAWK beacon signal. From pioneer to innovator the City of Tucson has modified the original HAWK crossing to accommodate bi- cyclists. These BikeHAWKs have two push-buttons one for pedestrians walking on the side- walk and another that can be reached by bi- cyclists still seated on their bikes and two crosswalks a tradi- tional white one for pedestrians and a green one for bicyclists. There are four BikeHAWKs on Tucson streets today with more in the works.
