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. 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.

Urban design
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.
