... 174 7. Chapter 7 Conclusions and Recommendations This research study investigated the safety effect of the retroreflectivity of pavement markings and markers on state maintained multilane freeways, multilane highways, and 2-lane highways in California.
From page 187...
... 175 retroreflectivity markings is approximately zero, for roads that are maintained at the level implemented by California. California's level of maintenance appears to be frequent with pavement markings being installed on higher volume highways up to three times a year with waterborne paint, or every two years with thermoplastic markings.
From page 188...
... 176 reasonable that the retroreflectivity of longitudinal markings and markers has an influence on the safety of access points. • The human factors of marker and marking visibility.
