Figure 3-5. Local Traffic Volumes Deleted
Figure 3-6. Settlement Traffic Volumes Deleted Travel Demand Travel within and outside of the community consists of individual trips. All trips have a purpose. Generators are the destinations of these trips - the reasons people travel. Some of the high traffic generators of the Meskwalu community include the casino, the Trading Post, the school, the health center and the tribal offices. Traffic generators outside the community's borders include nearby cities such as Tama/Toledo, Montour and Marshalltown. Accident Data Traffic accidents provide a degree of feedback on the relative safety of the transportation system. A problem may exist if a section of highway or a particular intersection exhibits an accident rate significantly higher than those of comparable facilities. Ascertaining the nature of the facility's particular problems is a major step in improving the performance of that system. By far, the most heavily traveled roadway near the settlement is US Highway 30. Due to the shear number of vehicles that travel this route, it has the highest probability for traffic accidents. Figure 3-7 shows the location and number of traffic accidents that have occurred along US Highway 30 in the vicinity of the settlement in the years 199 1 through 2000. Each line reflects an accident location. Dark lines represent "property damage only" accidents and light lines represent injury accidents. Only two fatal accidents occurred during this timeframe, and both of them are represented by circles. It is quite evident from Figure 3-7 that the location with the highest number of overall accidents (36), one being fatal, is the intersection of US 30 and the casino entrance. This intersection consists of what is essentially a two-lane access road crossing a divided four-lane highway. Traffic volumes in this vicinity are very high, and there are many turning movements being made into and out of the casino entrance. It should also be noted that the speed limit on US 30 is 55 miles per hour. The combination of high volumes, high speed, and turning movements is what makes this intersection so dangerous. In order to reduce the number of accidents at this location, the Tribe should meet with representatives from the IDOT to discuss alternatives for improving the safety of this intersection. Some options include: reducing the speed limit on US 30 in the area of the intersection, adding more advanced warning for users of US 30, building acceleration/deceleration lanes, and constructing an overpass.
