The City of Tucson DOT has implemented three traffic signals based on European techniques: the PELICAN Traffic Signal, the TOCAN Traffic Signal, and the HAWK Pedestrian Flasher. The City of Tucson Department of Transportation has implemented three traffic signals based on European techniques:

• The PELICAN Traffic Signal Pedestrian Light Control Activated, were initiated by the city using the European mid block pedestrian crossing technique of the same name. The technique incorporates a standard RED-YELLOW-GREEN signal indication method that rests in GREEN for vehicular traffic until a pedestrian wishes to cross. The signal then changes to YELLOW and then RED and a WALK light is shown to the pedestrian.
• The TOCAN Traffic Signal The signal system was designed similar to the European technique to provide a safe crossing for "two" groups-pedestrian and bicyclists, thus the name "TOCAN"or TwO (groups) CAN cross the roadway.
• The HAWK Pedestrian Flasher The signaling system is a combination of a beacon flasher and traffic control signaling technique for marked crossings. The Tucson High-intensity Activated crossWalK or HAWK crossing is an extension of the traditional school bus flashing warning signal when children are crossing the road and the European level or emergency crossing signal.
