CE 482 Geometric Design of Highways Lab No. 3 Q 1. The design of a highway section calls for an alignment consisting of three tangents. \( \begin{array}{ll}\mathrm{POT}_{1} 1 \text { to } \mathrm{Pl}_{1}, & \text { Length }=1336.860 \mathrm{~m} \\ \mathrm{Pl}_{1} \text { to } \mathrm{Pl}_{2}, & \text { Length }=874.020 \mathrm{~m} \\ \mathrm{Pl}_{2} \text { to } \mathrm{POT}_{2}, & \text { Length }=521.010 \mathrm{~m}\end{array} \) The deflection angles are: \[ \Delta_{1}=31^{\circ} \quad \Delta_{2}=66^{\circ} \] The station value of \( \mathrm{POT}_{1} \) is \( 188+000.000 \). If the final design of the highway uses a \( 551 \mathrm{~m} \) radius curve at \( \mathrm{Pl}_{1} \) and a \( 401 \mathrm{~m} \) radius curve at \( \mathrm{Pl}_{2} \). Determine the station value of the final alignment for \( P C_{1}, P T_{1}, P C_{2}, P T_{2} \) and \( P O T_{2} \)
