This often means that highway designers must think "outside the box" and find creative ways to incorporate new designs and travel alternatives that accommodate the concerns of diverse groups and a variety of system users. Further, the addition of new capacity presents an excellent opportunity to combine it with other types of strategies. In such locations, the addition of new capacity is critical. In those locations where the lack of physical capacity is the greatest contributor to congestion, addition of new capacity is critical. However, it is clear that adding new physical capacity for highways, transit, and railroads is an important strategy for alleviating congestion. In some metropolitan areas, however, it is becoming increasingly difficult to undertake major highway expansions because of funding constraints, increased right-of-way and construction costs, and opposition from local and national groups. Adding more lanes to existing highways and building new ones has been the traditional response to congestion. These fall into three general categories:Īdding More Capacity – Increasing the Number and Size of Highways and Providing More Transit and Freight Rail Service. Transportation engineers and planners have developed a variety of strategies to deal with congestion (Figure 4.1).
