Final Exam Review
The final exam will completely based on the Bearss Ave. project and plan set as posted
on the course website.
You need to know these plans very well.
Review my two lectures
where I reviewed the plans.
A typical question would be worded like, "On Bearss Ave,
why -----?, or "On Bearss Ave. designers now change a design choice, now what is the
value of ------?, etc."
There will be about 15 M/C questions on Quiz 1 topics: about 15 M/C questions on Quiz
2 Topics; about 15 M/C questions on Quiz 3 (New stuff) Topics:
Total 100 possible
Traverse calculations -- cartesian coordinates, route coordinates, northing, easting,
conversion between bearings, angles, and azimuths, computing N/E by "traversing" using
sine and cosine function, calculating the unknown distance and azimuth between two
coordinate points (inversing), determining the Linear Error of Traverse Closure, Ratio of
Error, balancing a traverse
Sample Calcs: Assume Sta 160 coordinates 10,000N/10,000E.
Compute the cartesian
coordinates of points on the Bearss Ave baseline, PCs, PTs, PIs.
Use the one given
azimuth (bearing), compute azimuths of lines on the baseline.
Calculate the unknown
straight line distance and azimuth between two alignment points (use distance formula
and atan for azimuth.
Horizontal Route Geometry and Design – route horizontal tangents, delta angles,
compute tangent lengths and azimuths, stationing, curve data and curve parts,
PC and PT
and PI stations, design to avoid overlaps, computing N/E coordinates of curve points.
Sample Calcs: Verify the Curve 3/4 curve data in the given tables.
Lets change one curve to a different curvature/radius, what is the new station of some
point? new curve data?
Compute the largest radius (minimum D) that would avoid
overlap between Curve 3 and 4, etc.
Vertical Route Geometry and Design --
