|Width Length and Height are only physical points of a vehicle and nothing to do of design of road because width, length and height are only come into consideration in turning manoeuvre.|
|Jay Mishra said: (Aug 28, 2014)|
|A road is totally design by speed of vehicle in friction, stopping distance, longitudinal slopes etc.|
|Shams Marwat said: (Sep 17, 2014)|
|Yes in the same way the superelevation of a vehicle is also designed by speed of vehicle. i.e. v*v/225R.|
|Sanjay said: (Oct 28, 2014)|
|Here it is true that the width, length and height does not provide any effect for worsting the alignment. Speed of the vehicle is the right answer.|
|Onkar said: (May 28, 2015)|
|Aspect related to roads are decided by speed of the vehicle, which shall work for any vehicle irrespective of the model.|
|Sabariii said: (Aug 24, 2015)|
|Width of the vehicle is influenced only in sight distance; otherwise speed of the vehicle is the right answer.|
|Revathi said: (Sep 2, 2015)|
|This is designed as per speed of the vehicle.|
|Neeraj Maurya said: (Oct 15, 2015)|
|Road design consider to the speed.|
|Santhi said: (Jan 27, 2016)|
|Because of pavement design is mainly depending up on the design speed of the vehicle.|
|Vikash said: (Jul 14, 2016)|
|Speed of vehicle is only involved as a variable while the other three parameters are taken as per IRC reccomendation. Thus ie speed which contributes a major role.|

|Width, length, height don't have any impact?|
|Dhananjay Singh said: (Dec 29, 2016)|
|Width length and height of vehicle are fixed parameter according to IRC and speed is variable for different speed SSD will be different so speed is considered to be worst (But at the time of designing of road length width and height of vehicle also considered).|
|Haroon said: (Mar 4, 2018)|
|Width:pavement width, shoulder & parking.
Length:radius of curve, extra widening, osd &ssd.
Height:vertical clearance & flyovers, electric poles.
Speed: gradient, superelevation, sight distance.
|Yash said: (Aug 30, 2018)|
|Speed is the major contribution of superelevation but in the road designing width height, length is also considered acc to IRC.|
|Arjun said: (Sep 16, 2019)|
|Speed is the overall function of Geometric design.|
