Geometric and PhysicalA list of physical features were listed on the inventory form. These items were checked when they were considered deficient. The top 5 problems are shown below. Exhibit C-3. Geometric/Physical Problems Inadequate shoulder width (insufficient width to accommodate a parked truck without hindering traffic flow), turning radii (right turning trucks are required to make wide turns into adjacent lanes), and lack of stabilized shoulders (shoulder not paved or not able to support heavy trucks) were the most prevalent problems. Inadequate travelway width ( roadway width is not adequate for two-way truck traffic) and flooding were also significant problems. Any one of these are a problem where heavy truck traffic is present. A number of connectors also showed multiple deficiencies. Exhibit C-4 shows that almost half the terminals have at least 2 deficiencies and 10 to 20 percent have 3 or more deficiencies. Exhibit C-4.
