Safety and security

Relative to other forms of transportation, public transit is safe (with a low crash risk) and secure (with low rates of crime). The injury and death rate for public transit is roughly one-tenth that of automobile travel. A 2014 study noted that "residents of transit-oriented communities have about one-fifth the per capita crash casualty rate as in automobile-oriented communities" and that "Transit also tends to have lower overall crime rates than automobile travel, and transit improvements can help reduce overall crime risk by improving surveillance and economic opportunities for at-risk populations."

Although relatively safe and secure, public perceptions that transit systems are dangerous endure. A 2014 study stated that "Various factors contribute to the under-appreciation of transit safety benefits, including the nature of transit travel, dramatic news coverage of transit crashes and crimes, transit agency messages that unintentionally emphasize risks without providing information on its overall safety, and biased traffic safety analysis."

Some systems attract vagrants who use the stations or trains as sleeping shelters, though most operators have practices that discourage this.
