Game Theory and ILP in Transit Policing: From Analog to DigitalSullivan JP; Los Angeles County Sheriff's Department jpsulliv@lasd.org

Los Angeles County Sheriff’s Department

Abstract: Policing urban mass transit systems (bus and rail) requires an understanding of threats, vulnerability, and criticality (impact) on the system and people. A range of hazards can potentially cause harm. These include crime, disorder, and terrorism. We are currently testing game theoretic modeling of a range of actors (police, transit personnel, passengers, and criminals) on the transit system. Balancing security, accessibility and legal concerns/liberty interests are key issues. Collaborative research between the University of Southern California, Center for Risk and Economic Analysis of Terrorism Events (CREATE) and the Los Angeles County Sheriff's Department, Transit Services Bureau (TSB) on the Los Angeles Metro system toward randomization and optimization of Intelligence-Led Policing (ILP): dynamic deployment and analysis for fare enforcement, disorder, crime, and terrorism will be highlighted.

METRO operates the third largest public transportation system in the US by ridership with a 1,433 sq. mi (3,711 km2) operating area

2,000 peak hour buses on the street any given business day

Metro also designed, built and now operates 79.1 miles (127.3 km) of urban rail service

The MTA has 9,200 employees

ARMOR-TRUSTS (Assistant for Randomized Monitoring Over Routes- Tactical Randomization for Security in Transit Systems) Pilot project with USC (CREATE) Randomization of fare operations, directed patrol

and special mission unit deployments; i.e. passenger screening & surge staffing

Uses game theory advanced quantitative statistics (econometrics)

Requires immersion of researchers and practitioner participation in practical field tests
