Developing a Low-Cost Safety Improvement Program for Intersections in an Urban Roadway Network: A Case Study

Table 5

Alternate safety countermeasures at a location.

Intersection	Countermeasure option 1	Countermeasure option 2	Countermeasure option 3
Oxford St. and Smith St.	Flashing red stop signs	Flashing signal	Roundabout
Clay St. and E. Lewis St.	Double centerline and stop bars	Transverse rumble strips	Roundabout
S. Coliseum Blvd. and E. Pontiac St.	Median (delineators)	Median (delineator) + warning signage	Centerline rumble strips
SR 1 and N. Clinton St.	Protected left + all clear phasing	Delayed red signal	Increase pavement friction
S. Anthony Blvd. and Chartwell Dr.	Dedicated left turn lanes	Dedicated left turn lane 0.94 s w/No lane Diet	Dedicated left turn lanes (1 approach)
Parnell Ave. and E. California Rd.	Install left turn lanes	Close the median
W. Rudisill Blvd and Fairfield Ave.	PPLT/FYA + all clear phasing	Increase pavement friction + PPLT/FYA + delayed red signal
St. Joe Rd. and St. Joe Ctr. Road	All clear phasing	Delayed red signal + increase pavement friction	Increase pavement friction
Maplecrest Rd. and Stellhorn Rd.	PPLT/FYA + all clear	Opposing left turns	Increase surface friction
Maplecrest Rd. and St. Joe Ctr. Road	Protected left only + all clear phasing	Protected left only (PLO)
