    6. Fall above
  7. 7There are 18 Factors to consider for a new alignment. Learn 5 of them for the test
    1. A1. keep grades and curvature to the minimum necessary to satisfy the service requirements of the highway
      2. Always provide adequate sight distance and avoid sudden changes in sight distance especially near intersections
      3. Avoid having a sharp horizontal curve on or adjacent to a pronounced vertical curve
      4. Locate the highway wherever possible along property boundaries not through the middle of blocks of land particularly farm land
    2. B5. Where it is practical maximize use of existing highway alignment to reduce land purchase costs
      6. Avoid areas or objects of historical, recreational or cultural significance
      7. Never have two roads intersecting near a bend or at the top or bottom of a hill
      8. Avoid at grade intersections with railway lines. If possible cross the railway where it enters a cutting
    3. C9. Keep road and stream crossing to a sensible minimum and if possible have crossing at right angles
      10. Avoid horizontal curves in bridges, tunnels or culvert structures
      11. Avoid where possible unstable ground prone to erosion or land slips
      12. Avoid low lying land prone to flooding
      13. Avoid if possible locations with rock close to the surface
    4. D14. In hilly terrain the highway should cross ridges at their lowest point. Avoid creating severe breaks n the natural skyline
      15. Minimize destruction of natural forest areas where some felling is necessary locate the road on a curve to preserve an unbroken background and minimize visual impact.
      16. Avoid placing a road at right angles to natural drainage pattern
      17. Balance volumes of cut and fill within a section of road to avoid need to purchase or tip large quantities of fill
      18. To relieve the monotony of driving on a long straight road it is an advantage to site it so as to give a view of some prominent feature ahead.
    5. EAll of the above
  8. 8The highway location process is an iterative (repetitive) one where a design is gradually refined until the most suitable location is decided upon.
    1. AVerdadero
    2. BFalso
  9. 9The highway location process is:
    1. A1. choose site
      2. buy the land
      3. decide where to place the road
      4. Draw it on a map
      5. Take it to council for approval
    2. B1. Fix end points of alignment
      2. Examine the region containing both end pints and all feasible routes between them
      3. Decide on a number of broad bands in which to concentrate further investigations (8 to 16km wide for major motorway)
      4. Narrow bands down to corridors 3-8kms wide
      5. Compare three corridors in detail and select the best
      6. Generate a route within the selected corridor 1-1.5km wide
      7. Search route area and locate one or more possible alignments up to 30 m wide
      8. Select final alignment
  10. 10What are the elements of a Roadway
    1. ALane
    2. BMedian
    3. CTraffic Islands
    4. DRight and left turn lanes
    5. EMedian openings
    6. FShoulder
