Strategic Modelling of Passenger Transport in Waterways: The Case of the Magdalena River

Abstract

In some Colombian regions, inland waterways play a relevant role in passenger mobility. However, many characteristics of their operation, required for planning purposes, are unknown. Existing data and studies are few and undetailed. In this context, collecting data and developing supply and demand models will make it possible to not only improving the knowledge of inland waterway transport in the country, but also the planning of the system. In this investigation, a survey instrument was designed and employed to collect data about passenger flows in seven ports on the Magdalena River, the most important river in Colombia. The collected information was used to specify and estimate strategic supply and demand models. Models based on the classic four-step model and alternative synthetic models were estimated and compared. The proposed models contribute to better understanding of the behaviour of inland waterway transport passengers. They were used to evaluate policies aimed at improving the users’ level of service and to encourage the utilisation of this mode of transport. Results show that accessibility variables and variables related to zone size define trip generation and distribution. In addition, it was found that inland waterway users in Colombia are highly cost sensitive.

COVID-19 Outbreak in Colombia: An Analysis of Its Impacts on Transport Systems

“…A highlight is that today freight transport operators are paying less for fuels and do not have to pay tolls. Furthermore, service provision is favoured by lower levels of congestion, which may have reduced its operational costs and externalities [41,42].…”

Sustainable development of inland waterways transport: a review

“…On the other hand, Trivedi et al (2021) argue that IWT poses numerous challenges to its implementation, being the lack of governance and policy the most critical barrier to developing IWT in India due to its inhibiting impact on other factors such as infrastructure improvements and the participation of the private sector because of the high costs associated with this type of transport. Finally, there is a need for available information and research to understand not only the unique hydrological characteristics of each basin but its commercial and infrastructure, and managerial requirements to support modal shift and policymakers' decisions to develop sustainable IWT systems (Berrio et al 2019;Vilarinho et al 2019).…”

“…IWT supports rural development and is relevant to passenger transport, especially in regions where road access is almost nil (Awal 2007;Berrio et al 2019;Vu 2011). In addition to that, IWT impacts the well-being of the citizens due to the increase in goods transportation and the positive effects of flood stabilization (Woś et al 2022).…”

Effect of Infrastructure Investment and Freight Accessibility on Gross Domestic Product: A Data-Driven Geographical Approach

“…erefore, the country has a low capacity for moving goods to international regions. As was mentioned before, many strategies are commonly applied for enhancing the transport system [8,9]. e most common is developing infrastructure investments to expand and improve roads, rivers, and rail networks.…”
