Transport Network and System of Cities

Urban Agglomeration and Dispersion: A Synthesis of Alonso and Krugman

“…Given the above parameter values, we first fix the value of f , and set initial values of x k 's. Then, w k 's are determined by (8), ϕ's are by (10), Y k are by (9), and z 1k 's are by (11) and (12). By putting these values into (13) and (14), we evaluate the differences between the right hand sides and the left hand sides.…”

“…There is another line of studies originating in Alonso [1], and extensively developed 1 Also see Mun [10] and Morisugi, Ohno, Ueda and Koike [9] although model structures are different, and see Fujita and Thisse [3] and Fujita and Mori [2] for detailed overviews on agglomeration and dispersion of economic activities.…”

Weber problem in the NEG: a case study of Asia

“…In a real geographical space, Stelder (2005) and Brakman et al (2006) simulate the location of cities in Western Europe using a large core-periphery model. By extending Mun (1997), Mun and Sasaki (2000) investigate the effect of providing a transportation infrastructure in the Tohoku area in Japan. This paper supplements the attempts of Stelder (2005) and Brakman et al (2006) in trying to predict the location of cities and agglomeration in a simulation.…”

Network Evolution With Cost-Benefit Evaluation Rules

“…The overall benefit by using the consumer surplus is simply calculated by applying the formula: (18) where B*is the naive measure of benefits gained by the improvement, Ri:i is the current OD trip volume,dij is transportation cost between node i and j before the improvement is made,and dZjis transportation cost after the (19) The demand function is defined by eq. (14).In calculating the change in Rij,the change of diJ in eq. (14)is only considered, while regional output Y,,is supposed to be unchanged.In case of the sophisticated rule,the calculations are made by considering both the change in the OD trip patterns and the sifts in the demand curves.…”
