Background information and definitions
It is likely that narrower roads are safer for primates to cross without injury compared to wider roads that they have to spend more time on. A study investigating the barrier effect of roads on the bank vole Clethrionomys glareolus, yellow-necked mouse Apodemus flavicollis and common shrew Sorex araneus found that species crossed narrow roads more often than wide roads (Rico et al. 2007). Therefore, reducing road width may help preserve habitat connectivity and prevent or reduce primate-vehicle collisions.
