Colombia necesita adoptar una agenda estratégica para poder atender el rezago en que se encuentra el sector de infraestructura de transporte. Dos reformas largamente aplazadas son determinantes para el éxito de esa agenda: Primero, aprovechar la oportunidad que representa la agenda de Cambio...

This paper analyzes the efficiency of and the substitutability between three urban congestion management policies: transit subsidization, car congestion pricing, and dedicated bus lanes. The model features user heterogeneity, cross-congestion effects between cars and transit, intertemporal and...

This paper investigates the relationship between the growth of road networks and regional development. We test for mutual causality between the growth of road networks (which are divided functionally into local roads and highways) and changes in county-level population and employment. We employ...

En Centroamérica las distancias son cortas y los volúmenes de carga son pequeños para consolidar una red densa de transporte marítimo de corta distancia. Además, no existe una red ferroviaria transnacional. Esto otorga al transporte automotor de carga (TAC) un rol clave en el transporte...

This study focuses on identifying the basic logistics capabilities in Belize, Central America and the Dominican Republic. It concentrates on the ports and sea network, taking into consideration intermodal networks involving both land and sea components together with the major performance drivers...

After analyzing logistics links between the ports of Cartagena (Colombia), Veracruz (Mexico) and Panama (Balboa and Colon) and their hinterlands, this study describes infrastructure restrictions as well as operational and institutional challenges for logistics development in Latin America and...

Distances in Central America are short and cargo volumes are small to build a dense network of short sea shipping. Furthermore, there is no transnational railway network. This gives trucking services a key role in international transport. This preliminary study characterizes trucking services in...

This paper analyzes the induced demand hypothesis using a disaggregate approach at the link level. A panel data set of Minneapolis/Saint Paul highway network for the years 1980-1998 is constructed. A model that predicts the traffic flow on the link in terms of Vehicle Kilometers Traveled (VKT)...

A multi-agent model of travelers competing to utilize a roadway in time and space is presented in this paper to illustrate the effect of congestion and pricing on traveler behaviors and network equilibrium. To realize the spillover effect among travelers, N-player games are constructed in which...

A number of factors influence the efficiency, productivity, and welfare of a transportation network. Travel demand, user costs, and facility supply costs equilibrate on various time scales under a set of pricing (taxes and tolls), investment and ownership policies. Two types of equilibria exist...
