MfS: 4.2.3 / MfS2: 1.2; 2.5                        
Direct frontage access on 30mph roads with up to 10 000 vehicles per day (e.g. distributor / collector roads in built up areas)
MfS: 4.2.3; 7.9 / MfS2: 9.10                        
CARRIAGEWAYS
20mph design speeds or lower for residential streets
MfS: 7.2; 7.4.2                         
20mph design speeds for streets with significant pedestrian activity, such as high streets or main streets 
MfS2: 8.2                        
30mph design speeds or lower for other streets in urban areas 
MfS2: 8.2                        
MfS recommended horizontal alignment 
MfS2: 8.3                        
MfS recommended stopping sight distances
MfS: 7.5 / MfS: 10.1 - 2                        
Restricted forward visibility to reduce vehicle speeds
MfS: 7.8 / MfS2: 10.3                        
MfS recommended junction visibility splays
