Today, an increasing number of necessary
infrastructural measures is encountered the purpose
of which is to assist in managing the traffic speed
thus forming the most important part in speed
management policies. This paper reviews the choice
of permitted driving speed depending on the defined
street category. The existing norms that define road
functions and categories for the urban street
network in Latvia are evaluated. This paper stresses
the need to review the functional classification of
the road network with specific attention paid to the
importance of each road type and their influence on
the drivers’ choice of adequate driving speed. A
practical study on the efficiency of the chosen road
profile (number of lanes, median, etc.) and design
parametres (width of driving lanes, longitudinal
curvature radius, horizontal curvature radius, etc)
in the existing street network has been performed. |
