![]() For example, the surfaces with bumps and positive and negative cleats are used to study low frequency ride performance when the tire is subjected to larger excitation inputs. These surfaces, with different textures and features, replicate different real-world roads with different road profile excitation frequencies and amplitudes. The vehicle is usually tested on different road surfaces. Yousof Azizi, in Automotive Tire Noise and Vibrations, 2020 5.3.2.1 Outdoor objective evaluation: structural borne noise This chapter will not go into details concerning the design of the different solutions and their variants, but will instead concentrate on giving the arguments and the criteria for the choice between integration, visual segregation and physical segregation. If sufficient room is available, a verge of a certain width is preferred in order to create a safety margin between cyclists and motorists. īicycle routes following their own line −īicycle tracks alongside roads for motor traffic (a)Ī physical segregation can be achieved in various ways, e.g., by a verge between the carriageway and the bicycle track by creating merely a difference in level between carriageway and bicycle track or by putting a fence in between. ![]() Virtual bicycle lanes (lanes which have no bicycle logo and no legal status, but which do suggest that cyclists will use this lane). īicycle lanes (which have a bicycle logo on the pavement in order to give them a legal status) −.With or without (speed and/or intensity) restrictions for motor traffic. One way streets allowing cyclists in the opposite direction − No segregation but integration of different modes: − In the discussion on integration and segregation we can distinguish between: As an introduction we start with a list of conceivable forms of integrated and segregated road profiles (asterisks note the most common types of physical segregation in The Netherlands).
