Beginning the the early 20th century, the 1920's saw several major advancements. There was improvement in rural roads which was significant for the time.The diesel engine, which are 25-40% more efficient than gas engines were also a major breakthrough.We also saw the standardization of truck and trailer sizes along with fifth wheel coupling systems. Additionally power assisted brakes and steering developed. By 1933, all states had some form of varying truck weight regulation.
The decade of the 70s saw the heyday of truck driving, and the dramatic rise in the popularity of "trucker culture". Truck drivers were romanticized as modern-day cowboys and outlaws (and this stereotype persists even today). This was due in part to their use of citizens' band (CB) radio to relay information to each other regarding the locations of police officers and transportation authorities. Plaid shirts, trucker hats, CB radios, and using CB slang were popular not just with drivers but among the general public.
The United States' Interstate Highway System is full of bypasses and loops with the designation of a three-digit number.Usually beginning with an even digit, it is important to note that this pattern ishighlyinconsistent. For example, in Des Moines, Iowa the genuine bypass is the main route.Morespecifically, it is Interstate 35 and Interstate 80, with the loop into downtown Des Moines being Interstate 235. As itis illustratedin this example, they do not alwaysconsistentlybegin with an even number.However, the 'correct' designationis exemplifiedin Omaha, Nebraska.In Omaha, Interstate 480 traverses the downtown area, whichis bypassed byInterstate 80, Interstate 680, and Interstate 95. Interstate 95 then in turn goes through Philadelphia, Pennsylvania. Furthermore, Interstate 295 is the bypass around Philadelphia, which leads into New Jersey.Although this can all be rather confusing, it is most important to understand the Interstate Highway System and the role bypasses play.
Full truckload carriersnormallydeliver a semi-trailer to a shipper who will fill the trailer with freight for one destination.Once the traileris filled, the driver returns to the shipper to collect the required paperwork.Upon receiving the paperwork the driver will then leave with the trailer containing freight. Next, the driver will proceed to the consignee and deliver the freight him or herself. At times, a driver will transfer the trailer to another driver who will drive the freight the rest of the way.Full Truckload service (FTL) transit times are generally restricted by the driver's availability. This is according to Hours of Service regulations and distance.It istypicallyaccepted that Full Truckload carriers will transport freight at an average rate of 47 miles per hour. This includes traffic jams, queues at intersections, other factors that influence transit time.
Relocation, or moving, is the process of vacating a fixed location, such as aresidenceor business, and settling in a different one.A move might be to a nearby location such as in the same neighborhood or a much farther location in a different city or even a different country.Moving usually includes packing up all belongings, transferring them to the new location, and unpacking them. It will also be necessary to update administrative information. This includes tasks such as notifying the post office, changing registration data, change of insurance, services etc. It is important to remember this step in the relocation process.
The American Association of State Highway and Transportation Officials (AASHTO) conducted a series of tests.These tests were extensive field tests of roads and bridges to assess damages to the pavement.In particular they wanted to know how traffic contributes to the deterioration of pavement materials. These testsessentiallyled to the 1964 recommendation by AASHTO to Congress.The recommendation determined the gross weight limit for trucks tobe determined bya bridge formula table. This includes table based on axle lengths, instead of a state upper limit. By the time 1970 came around, there were over 18 million truck on America's roads.
