As part of the N Euclid Neighborway Project, DOMI ran a pilot of the Neighborhood Traffic Circles at four intersections along the corridor. The pilot has been up for a month, and during that time, DOMI collected data, interviewed stakeholders and neighbors, and took video footage to analyze the effect of the intervention.
Miovision Camera and Speed Data collected between July 9 and July 21
DOMI installed a Miovision Camera at Euclid & Callowhill since buses use this intersection. The devise recorded before and after the splitter island was installed. The focus of recording includes: Use of the traffic circle; Type of vehicle making incorrect turns; Time stamps of near misses or concerning behavior; Outreach and education; Pedestrian and bicyclists; Large vehicle behavior.
Found: 1,208 vehicles, with 22 (2%) using the intersection improperly, with 3 “near miss” incidents with no crashes.
Speed Data: Euclid at Callowhill showed average speeds of 19 mph. The vast majority travelled through below the speed limit. Euclid at Paca Way showed average speeds of 21 mph. Once all seven traffic circles are installed, there is expected to be a network effect of slower speeds along the full corridor.
Field Visits, Survey and Neighborhood Interviews
Survey: During the Pilot, DOMI launched a survey to collect info from residents. Between April 17 and July 30, a total of 161 people responded to the survey, with 83 Positive, 55 Negative, and 23 Indifferent responses.
