Example of a district map showing: • narrow roads (<24 ft.), • crashes on horizontal
curves, and • crash locations
qualifying for additional paved surface width (WC 541)
14
Example of a county map showing crash locations qualifying for: • installing traffic
signals (WC 107), • improving traffic
signals (WC 108), and
• interconnecting traffic signals (WC 111)
