Survey Safety

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Area of Science:

Road safety
Transportation engineering
Urban planning

Background:

Personal mobility vehicles (PMs) are increasingly popular globally.
Increased PM use has led to a rise in accidents involving PM users and other road users.
Existing regulations on PM use, such as on sidewalks, are often not well-enforced.

Purpose of the Study:

To identify risk factors for personal mobility vehicle (PM)-related accidents.
To analyze injury severity in PM-related accidents.
To explore potential solutions for enhancing PM user safety.

Main Methods:

Utilized the Traffic Accident Analysis System (TAAS) data from South Korea (2017-2019).
Analyzed accident data to identify correlations between road infrastructure and PM-related incidents.
Examined factors contributing to accident occurrence and injury severity.

Main Results:

PM-pedestrian accidents are more common on roads with wider sidewalks and bike lanes.
This road configuration may increase pedestrian-PM conflict.
Roadway use by PMs presents a higher risk of collision with motor vehicles.

Conclusions:

Expansion of physically separated bike lanes and sidewalks is recommended.
Stricter enforcement of safety rules for PM users is necessary.
Integrated infrastructure and regulatory approaches are needed to improve PM safety.
