This document appears to be an exam for a Transportation Engineering course, consisting of two pages with multiple choice and short answer questions. Some of the key topics covered include: - Expressways, camber factors, enoscopes, permanent ways, ground speed vs air speed. - Drawings for highway projects, grade compensation on curves, traffic volume data presentation, ballast renewal. - Star and grid intersection patterns, overtaking sight distance calculations, advantages of rotary intersections, components of turnouts. - Runway length calculations factoring in elevation, reference temperature, and gradient. - Highway alignment points, final location and detailed surveys. - Superelevation calculations, sle
