Smartphones and pedestrian safety

Safety hazards have been noted due to pedestrians walking slowly and without attention to their surroundings because they are focused upon their smartphones. Texting pedestrians may trip over curbs, walk out in front of cars and bump into other walkers. The field of vision of a smartphone user is estimated to be just 5% of a normal pedestrian's.

Some cities have taken design measures to make the streets safer for inattentive pedestrians, including lights embedded in pavements, and dedicated lanes for smartphone-using pedestrians to use.

The pejorative term smartphone zombie has been used to describe inattentive phone users; this phrase was sometimes blended to Smombie in German and has seen some English usage. In Hong Kong such phone users are called dai tau juk ("the head-down tribe"). A 2017 review considered the popular culture term in regards to the medical diagnoses of internet addiction disorder and other forms of digital media overuse.

In 2016 the American Academy of Orthopaedic Surgeons created a "Digital Deadwalkers" awareness campaign, in response to the risks associated with walking across intersections and sidewalks while paying attention only to smartphones and not one's surroundings. They characterised such pedestrians as "oblivious to everyone else, so it's like they're dead-walking, sleepwalking".

An association between problematic mobile phone use and a greater risk of simultaneous mobile phone use and road use and risk of vehicle collisions and pedestrian collisions or falls has been found.

In Chongqing, China, the government constructed a dedicated smartphone-sidewalk in 2014, separating the phone users and the non-phone users. A similar scheme was introduced in Antwerp the following year.

In Augsburg, Bodegraven and Cologne, ground-level traffic lights embedded in the pavement have been introduced so that they are more visible to preoccupied pedestrians, while traffic signals at an intersection in Zagreb cast the red light downwards, producing glare on smartphone screens.

In Seoul, warning signs have been placed on the pavement at dangerous intersections following over a thousand road accidents caused by smartphones in South Korea in 2014. The city has also implemented traffic lights embedded into the ground to pass the indication to the pedestrian even if they are fully immersed in their smartphone experience.
