1 hour. These improvements seem reasonable to expect as the land adjacent to the two P P J roads is developed. I The first ultimate assignment was made on the existing street network with the g g modifications noted above. The forecast ADT volumes are shown in Figure 3. The Iresults identified system deficiencies, locations where demand exceeded capacity. Two remedies were possible: increase capacity on existing roads or add roads to the I system. It was not expected that either could solve all the deficiencies alone, but rather that a combination of the two would be necessary. With this in mind, an attempt was made to identify roadway segments to be added to the network that 1 111 would have the greatest impact on the deficient areas, whose addition would have • enough effect to at least make it practical to solve the remaining deficiencies with capacity improvements. The options for roadway improvements were often limited I by geographical features and existing development patterns,particularly residential development. IAdditional ultimate assignments were made with various roadway additions to determine the impact of their presence on the functioning of the remainder of the roadway system. Further discussion of system deficiencies and roadway additions Ican be found in the next sections of this report. D. Development of Transportation Plan The objective of a transportation plan is no different from that of other long-range I plans: to anticipate problems, find solutions, and develop an implementation process. Anticipation of problems comes in the form of identifying system, deficiencies on the planning horizon. Solutions are the actions taken to remedy the I deficiencies,whether in the context of the existing roadway system or by adding new segments to the network. Implementation answers the question of how to go about taking these actions; when they should be taken, in what order, and how to fund I them. I It is important to recognize that travel demadn forecasting is not an exact science. Every attempt is made to follow standard practices and incorporate information unique to the study area into the forecasting process. However,many factors out of I the planner's control can affect automobile travel. Some of these are cost and availability of fuel,transit use, average household size and perceived desirability of making a trip of a certain length. Awareness of these factors is particularly necessary I when the forecasting horizon is distant, as is generally the case with a forecast of ultimate development. The number of years it takes the City to reach the point of ultimate development has a significant bearing on what the external traffic volumes Ientering and departing the network will be. Functional Classification Ii. Before specific deficiencies and remedies are examined, it is appropriate to p define the term "functional classification" and describe how the ultimate Itransportation system in the City of Elk River must take the shape of a working functional classification system. A functional classification system ICTP-230.156 -1 g 230-156-80
