Growing up in a suburban town in the 1970s and 80s, my awareness of traffic engineering practices was fairly run-of-the-mill, especially for someone who didn't give any thought to a career in transportation until college. Our community had the typical street network with a handful of traffic signals, a rail line running through it, and a major interstate that connected us to the beach in Galveston, TX, USA and the big city of Houston, TX. Like most of my peers, I learned to drive at 15, navigating typical Texas roadways with little variety as to their design and operation. My first exposure to a different type of intersection control was at the age of 19, riding through a roundabout in England on the left side of the road with the driver on the right side of the car—talk about culture shock! I also appreciated the messages on the pavement at crosswalks in London telling pedestrians to look right for oncoming traffic. |
