Speed Management on Icy and Snowy Pavement of Urban Road

Abstract:

Icy and snowy pavement create obvious adverse impacts on road safety so that speed management is necessary for safety. According to the analysis of driver’s brake reaction time and vehicle’s brake distance on icy and snowy pavement, automobile’s parking distances were calculated and given under the condition of different speed and icy and snowy pavement types through observed friction coefficient data of snowy pavement, rough icy pavement, smooth icy pavement and icy-snowy pavement. The calculation method of maximum safe speeds under the condition of different icy and snowy pavement types and traffic volume were put forward. And suggestion values of car’s maximum safe speed when driving on icy and snowy pavement were given.
