Modelling Internal Migration in Kenya: An Econometric Analysis with Limited Data
In this paper the determinants of internal migration in Kenya are analyzed on the basis of a human capital model. Explanatory variables included in the specification are both economic (wage rates and employment rates) and noneconomic (for example, population density and educational attainment). Also incorporated are variables which reflect intervening opportunities. These variables are defined as distance-weighted averages of the variables in all…

A Theoretical Model of Road Development Dynamics
In this paper a recursive version of a dynamic road investment problem is developed by extending the Ellet-Walters developmental model of transportation so as to account explicitly for the effects of road investment on the supply and demand of the port hinterland's product. An explicit lagged supply function that depends upon commodity price and road penetration is related to a given linear demand function, assuming annual market clearance. A rec…
Regional Transport Investment Planning∗
Regional transport investment planning has traditionally assumed that virtually all the relevant information necessary to successful planning is known with complete certainty. More realistically, these investment decisions can be viewed as taking place in an environment where most of the necessary information is not known with any degree of certainty and where unpredictable events might alter the suitability of investment decisions made at a prev…
Optimization Models of Transportation Network Improvement
Urban Population Distribution Planning
Public policy objectives concerning urban population distribution often are achieved through residential land use regulation. Control over population distribution also can be exerted indirectly through the selection of employment sites. If population policy goals can be expressed as a target for each zone of the urban area, then it is possible to determine that spatial distribution of employment for which population distribution comes as close as…
Sequencing Highway Network Improvements: A Case Study of South Sulawesi
A common problem in transportation planning studies is to determine which improvements or additions to a transportation network should be made within some given planning horizon, and then to sequence the construction of these projects in some optimal manner. Mathematical programming models capable of solving simultaneously the project selection and timing problems are computationally demanding, and, as a result, it is often necessary to resort to…
Land-Use Plan Design via Interactive Multiple-Objective Programming
An urban land-use plan-design model is cast as a multiple-criterion optimization problem and is solved by using a generalized interactive technique. Three different objectives are selected for use in a representative formulation: (1) the minimization of land-development costs, (2) the maximization of residential accessibility, and (3) the minimization of energy consumption in transportation. It is found that interactive multiple-objective program…
A Mathematical Programming Approach to a Network Development Problem
The allocation of investment to a transportation system cannot be prescribed without accounting for the interdependencies that relate the transportation system to the larger economic system of which it is a part. Like all other sectors of the economy, the transportation sector must function within the operating conditions and constraints determined by the other sectors of the economy. In turn, the transportation system influences the performance …
