UBC Okanagan research has found that high-visibility vests with arrows may curb traffic accidents and cyclist fatalities.

Gordon Lovegrove, a UBC Okanagan associate professor in the School of Engineering, and industry collaborator Takuro Shoji, conducted road tests with cyclists in Kelowna between 2016 and 2017.

According to Lovegrove, the tests were done to determine the role communication plays in the safety of vulnerable road users.

For the initial road test, a total of 25 participants either wore the high-vis clothing they usually wear or a proprietary visibility vest called ArroWhere with an arrow design directing traffic away from pedestrians and cyclists.

The participants rode bikes equipped with inertial sensors, proximity sensors, and video recorders, all of which monitored rider position in relation to passing traffic separation and distance.

Before and after the rides, they also filled out surveys about their perceived safety and comfort.

According to the , the results of the initial road test suggested that riders felt safer wearing ArroWhere and that passing cars drove by in a safer manner.

The researchers then conducted an online survey with 103 participants and another in-field test, where a total of 85 participants rode a two-kilometer stretch of urban collector in a bike lane, wearing ArroWhere designs.

The overall results, which were published this month in the journal Sustainability, indicated that traffic provided wider berths when the riders were wearing reflective apparel with an arrow symbol.

Visibility is key to reducing vehicle-cyclist collisions, Lovegrove said, however, 91裸聊视频渆vidence suggests that current conspicuity aids cannot provide sustainable safety in their current form, and a more optimal design is needed.91裸聊视频�
