(1) Answer:- Decision criteria for alternative route selecting:-
(i) Optimize alignment
(ii) Connections
(iii) Costs
(iv) Benefits
(2) Answer:- (i) Community Accessibility
(ii) Horticulture effect
(iii) visual impact
(iv) Noise
(v) Property
(3) Answer:- Public hearing is very important in route survey. Because many private properties may be in route. If route is Passing from populated area then public hearing is very necessary.
(4) Answer:- Location is very important in route selection. Location should result in minimum interference to agriculture and industry.Location should as for as possible facilitate easy grades and curvature.
(5) Answer:- Topographical maps
(6) Answer:- Geological maps
(7)Answer:- Reconnaissance survey
(8) Answer:- Preliminary survey.
To determine for greater accuracy the cost of estimation done in preliminary survey.
(9) Answer:- Theodolite
(10) Answer:- Detailed survey
