An intersection has 4 approaches: north, south, east and west, with the following design volumes: north approach: sbt 440 vphpl, sbl 121 vphpl south approach: nbt 396 vphpl, nbl 103 vphpl east approach: wbt 292 vphpl, wbl 31 vphpl west approach: ebt 133 vphpl, ebl 44 vphpl each approach has 4 lanes: 1 left-turn lane, 2 through lanes, and 1 right-turn lane. the right-turn volumes are not considered in the design because all the approaches have a right-turn lane. draw this intersection, its 4 approaches (with north pointing up), the 4 lanes per approach and 8 arrows for the 8 through and left-turn movements. write the nema numbers 1 to 8 next to these arrows.
