The Southeastern Pennsylvania Transportation Authority this week released a comprehensive plan to address the safety and security of the system’s vulnerable population.

That population includes individuals experiencing homelessness, substance abuse and mental health issues, SEPTA officials said in a press release. The population has grown in recent years, which prompted the launch of the Safety, Cleaning, Ownership, Partnership and Engagement (SCOPE) program last year…

In its first year, the SCOPE program has mobilized partnerships with government entities, nonprofit organizations, businesses and academic groups that work to address these challenges. SEPTA has also upgraded its security measures, increased the frequency of system cleaning and expanded the number of social service outreach workers on the system from seven to more than 50.
