Your suggestion worked perfectly. See my update to my original post. Thanks.

@nikie: I added an image to my original post that helped me understand your explanation of xTotal=15-x[15]/.sol.

@nikie: Wow! An absolutely incredible explanation. May I ask two more questions. First, t is really s or arc length, correct? Second, how does tTotal=15-x[15]/.sol work? I understand the /.sol part, but where does the 15 come from?

comment Curvature Application
My next question would be a needed explanation of {(t - 1)*4*(Pi/tClothoid^2), t < 1 + tClothoid/2}, . What does this mean? It obviously gives the left side of the triangle in the lower figure and maybe the first half of the clothed in the upper figure, but why? Very hard for a rookie to understand.

comment Curvature Application
The main part I don't understand is how you came up with the curvature function in your opening steps. Could you first explain tClothoid = 2/FresnelS[1]; What does FresnelS[1] return, and why divide 2 by the result?

comment Curvature Application
This is absolutely magnificent and something I would like to truly understand. The first difficulty is that most books or articles on differential geometry spend a lot of time on proofs of theory but do very few, if any, examples. I've done some searching online, but I haven't been able to find what I need to understand this answer. Can you point out an article that does a number of examples of the Fundamental Theorem of Plane Curves, Existence?

@Mr.Wizard. It does work. See my edits to the my original post. What I am really thinking about is if such and such is true, then I am going to write a number of steps. My approach above does do some nice indentation and makes things easier to read and understand, but is it the best approach?
