Parameters (3) vehicle type

So far I have discussed the concept of fundamental parameters in highway geometric design (for example, here) and the fundamental parameter “road type“. This post covers the fundamental parameter “vehicle type“. Vehicle type relates directly to design vehicles – the … Continue reading

Parameters (2) road type

I began a discussion about fundamental parameters in highway geometric design recently. The first parameter in my list is road type.  A feature of “road types” is  that they are associated with specific details of highway geometric parameters in all … Continue reading

New road classification / 4 : a two-dimensional geometrics classification

The previous post in this series gave an example of a two-dimensional classification for roads, and asked: What would be the features suitable for use in a 2-dimensional code for the geometry of roads? The same post argued that when … Continue reading

Classification for design – FOUR main road types ?

In an earlier post (here) I argued that there are in effect only two types of road. For example I said that:
