( ) Check: C = 80 = G1 + G2 + G3 + 3*(Y + AR) = 16.3 + 30.6 + 18.7 + 3*(3 + 1.8) = 80 If you chose 2 phase as ideal: ( ) Check: C = 60 = G1 + G2 + 2*(Y + AR) = 36.3 + 14.1 + 2*(3 + 1.8) = 60 If you chose 4 phase as ideal: ( ) Check: C = 110 = G1 + G2 + G3 + G4 + 4*(Y + AR) = 22.0 +41.2 + 8.3 + 20.0 + 4*(3 + 1.8) = 110 Problem 4 (10 pts.) First, we will need to divide our volumes by our PHF of 0.93. We receive: Approach Left-turn volume Through volume Right-turn volume Northbound 130 436 151 Southbound 88 347 138 Eastbound 467 583 173 Westbound 240 524 182 Eastbound 491 583 182 Westbound 252 524 192 Next, we will need to apply the multiplication factor Approach Left-turn volume Through volume Right-turn volume Northbound 390 436 159 ( ) ( Southbound 264 347 145 ) ( ( ) ( )) Problem 5 Advantages: 1. Provide orderly movement 2. Increase capacity 3. Increase safety (reduce severe/certain crash types) 4. Coordinate traffic flow for continuous movement 5. Introduce gaps 6. Allows for safe pe...
