Tunnel Road Safety: A Look At Older Drivers’ Performance And Sight Impairment, Edith Lopez Mar 2014

Tunnel Road Safety: A Look At Older Drivers’ Performance And Sight Impairment, Edith Lopez

Master's Theses and Project Reports

In California, there is an observed trend in which collisions cluster in and around tunnels. The break in road continuity created by the tunnels disturbs traffic flow that can lead to collisions. One of the main contrasts between open roads and tunnel roads occurs in lighting. Drivers with sight deficiencies are unable to adapt their sight to the change in the lighting environment and may crash due to misperception of road alignment, vehicle’s speed and other physiological reactions, such as tension. The suspect population group of crashes occurring under the influence of tunnels conditions is older drivers.
