21 conducted traffic enforcement operations and distributed safety tip handouts to both motorists and pedestrians. LACMTA organized the multi-jurisdictional committee of law enforce- ment. Although the primary thrust of the operation was safety education, law enforcement did issue citations to members of the public who flagrantly violated traffic safety rules (14). Photo Enforcement In an effort to reduce risky behaviors such as driving around crossing gates and running red lights, LACMTA has success- fully used photo enforcement at both gated and non-gated crossings. Along the Metro Blue Line, LACMTA uses photo enforcement to cite drivers for running red left-turn arrows and, as a result, accidents caused by motorists making illegal left turns have been reduced by 62% since left-turn enforce- ment began in 2004 (15) (Figure 25). OTHER Lower Train Speeds TriMet began operation of their MAX Yellow Line in May 2004 with trains operating at 30 mph, as opposed to 35 mph. Although they originally had plans to raise the speed to 35 mph, they have not yet seen a reason to do so. In more than FIGURE 25 Photo enforcement camera (Courtesy: Los 3 years of operation, they have only experienced 11 left-turn Angeles County MTA). collisions, which have been widely distributed across the many crossings along the corridor, and are believed to be the result of in part to the lower operating speeds.
