Exhibit 2: Number of Crashes Over 12 Weeks
Description
From the article ""Effect of High-Visibility Enforcement on Motor Vehicle Crashes," June 22, 2020.
HVE reduced the number of crashes at target sites for three weeks before the number began to trend upwards. A dosage of two hours a day of HVE for two days every three weeks reduced the crash numbers at hot spots compared to those at the control sites. Dashed lines denote weeks of HVE at target sites.
