This consists of a detailed list of considerations to be used in negotiating a set of
road standards in an environment. This includes the following:
1. Resource management objectives: These indicate the reasons and
purpose a particular road should be built in a particular area. For instance,
it may have to do with the economic benefits derivable in such an area
when the expected road is constructed e.g. access to rural community for
easy transportation of agricultural produce.
2. Physical environmental factors: The topographic, climatic, soil and
vegetative characteristics of an area, the physical features of the land as
well as the type of road to be constructed and so on must be determined if
a road must be built in that area or not.
3. Environmental limitations: There are social-political limitations e.g.
erosiveness of soils, difficult geologic conditions, high rainfall. Others
include land ownership boundaries, state of the local economy and the
public opinion about the given project.
4. Traffic requirements: The average daily traffic should be estimated for
different user groups and the traffic volume will also determine the kind of
road needed in such an area.
5. Traffic service level
