Pre-Design Considerations Site Analysis Before creating a design, traffic engineers need to conduct a site analysis to determine what needs the site may have for the area’s traffic. They will need to take note of the surrounding area – businesses, schools, railways, protected lands, etc. – and investigate any local policies that might affect their work. Traffic Surveys A traffic survey is a survey conducted by traffic engineers to determine how traffic moves through a particular area. These usually take 2-4 days per intersection to complete and need to occur throughout the day to ensure both peak and non-peak hours are factored in. One of the most popular ways a traffic survey is conducted is with the use of rubber hoses. These hoses run across the road and connect to a meter that counts each vehicle that passes while also determining what type of vehicle it is. These hoses also collect data on what speed the vehicle is going when it passes over the hose. Traffic engineers...
