Urban Economics: Theories
Congestion Theory and Transport Investment by William S. Vickrey Congestion Theory and Transport Investment identifies the major problems of traffic congestions. The findings in the article are based on empirical evidence and calculi and it is written in a formal and specialized style, addressing as such the expert in urban economics. The ten page article is structured into seven parts: 'Deepening' and 'Widening' of Transport Investment, Types of Congestions, Accidents as a Cause of Congestion, Construction to Ease Bottlenecks, Expansion of Routes in the Presence of Alternative Routes, Variations in the Value of Time and Evaluation of Investment in Congestion Relief.'Deepening' and 'Widening' of Transport Investment'Deepening' and 'Widening' of Transport Investment emphasizes on the need to analyze various forces before establishing the necessary investments to be made in transportation channels. These factors that must be taken into consideration according to Vickrey include the marginal cost, congestions, bottlenecks, existing and alternative routes as well as consumer surplus. Due to a lack of adequate analysis and implementation of these forces, the current transportation networks in cities are under-developed as th
5 billion are attributed to increased fuel consumption resulting from congestion-induced drops in fuel efficiency" (Nechyba and Walsh, 2004)reduced housing developmentsdeclining sense of communitytoo much reliance of personal automobilesreductions in the agricultural land, which is now transformed into real estate and living property, anda drastic separation between the workplace and the residential areas (Nechyba and Walsh, 2004). urban landscape resulted from a combination of car purchases, large public investments in road infrastructure, limited public investment in central cities, the existence of much population heterogeneity within cities and low cultural barriers to household mobility. Types of CongestionsTypes of Congestions identifies and explains six types of situations that often occur within cities; the author states that these types of congestions may appear as such or in combination amongst themselves. In the middle nineteenth century, the general perception of urban sprawl was that it negatively impacted the community's development and negatively affected the population in terms of economics and social organization. They base their findings on a combination of the costs and benefits deriving from the city models of urban organization and their results include the following limitations:the loss of open space in the suburbsurban decayincreased pollution in the urban air and waterlarger numbers of traffic congestions; "for instance, a study of 75 U. The model takes various factors into consideration when analyzing sprawl, factors including commuting and transportation costs (implemented within the monocentric model), but also existence and proximity to schools and other educational, professional or recreational facilities, and social factors such as crime rates in the region. This is especially likely to be the case where charges levied for the use of the existing and prospective competing facilities are far wide of the mark of representing marginal cost, as they often tend to be" (Vickrey, 1969). In this particular meaning, he identifies two forces that had been overlooked in analyzing the costs of congestions: delays and accidents. A major factor to be considered in this equation is the time value of each commuter and the length of the vehicle queue, all affecting the discontinuity and various levels of delays. Vickrey discusses the road capacity in terms of current capacity, potentially smaller and potentially larger capacity. Evaluation of Investment in Congestion ReliefEvaluation of Investment in Congestion Relief is the last stage of Vickrey's approach to traffic congestions and it emphasizes on the need to clearly analyze the costs involved before setting the budget for the investment. Vickrey's predecessors have often said that the poor are disadvantaged in traffic as they are forced out of the highways.
