Question
Chapter 14, Problem 1P
To determine
The three categories of information gathered in the office prior to any field
Expert Solution & Answer
Explanation of Solution
The three categories of information gathered are:
- Engineering: It includes topography, geology, climate, and traffic volumes.
- Social and Environmental: It includes land-use and zoning patterns.It also includes types of wildlife; location of recreational, historic and archeological sites and the possible effects of air, noise, and water pollution.
- Economy: It includes unit costs for construction and the trend of agricultural, commercial and industrial activities.
These data can be obtained from existing engineering reports, maps, aerial photographs and chartswhich are usually at one of the state agencies such as departments of transportation, agriculture, geology, hydrology and mining. The type and amount of data collected and examined depend on the type of highway being considered.
Conclusion:
Preliminary analysis of the data will suggest if any of the specific sites should be excluded from further consideration.

THREE QUESTIONS ANSWER TWO
Question 1
a) As a Highway Engineer, you have been tasked to located a road
between Kyerekom and Abease communities. Table 1 presents the
characteristics of alternative routes A, B, and C established during a
reconnaissance survey out of which the best route is to be selected
for further investigation in the next stage of the location process.
After a critical evaluation of the characteristics of the routes, which
route will you select as the most feasible and why?
