Access management major Roads Dominican Republic, traffic simulations and scenarios analysis. This study approaches the concept of Highway Access Management from three perspectives: capacity, safety and economic impact. Five major roads of the Dominican Republic were analyzed, including a total of 13 intersections and 2 links in main cities. The data collection included traffic counts (2016) and number of accidents (2008 and 2015).
As general conclusion, this work shows that LOS is very subjective from the user’s perspective, and that constant speed is a key issue in major roads. However, corrective infrastructure measures can unequally affect distinct groups of the population, despite the guidelines. Up to the author’s knowledge, this is the first work about access management and equity of infrastructure in Latin-America.

Value of time in Dominican Republic: Contributed to transport models for Dominican Republic in collaboration with Louis Berger.
In this study we corrected the VoT by adding an scale factor of education level in the utility function. Additionally, we corrected the unobserved factors of taste variation of respondents, by controlling the panel effects (effect of repeated choices by the same respondent). The VOT, for the case or road pricing WTP, is a crucial issue in the design of toll. As can be seen, the new VOT increased the traffic volumes substantially, as expected.
In the Southwing of the Netherlands, local and regional governments, NS and Prorail voluntarily work together to implement a regional Transit Oriented Development (TOD) programme called Stedenbaan.
The University of Twente, Delft University and VU University Amsterdam have started a new 2-year research programme, funded by the Netherlands Organisation for Scientific Research (NWO). The programme comprises three postdoc projects and aims to contribute to the development of effective and economic efficient regional TOD strategies for StedenbaanPlus on the short and medium term. Firstly, the degree to which improving station accessibility can be an alternative development strategy for urban densification around railway stations, given the decreased demand for new housing and office locations at the short term, is examined, using accessibility modelling and conjoint analysis. Secondly, the extent and conditions under what users are willing to attune their residential and work location choices and travel behaviour on the TOD model is examined, using conjoint analysis. Thirdly, the social costs and benefits of TOD are examined, based on a urban economic model, taking into account competition by municipalities for individual TODs. Finally, recent insights on transferability be used to what extent factors contributing to successfully implemented TODs in Europe and the USA can be transferred to the Stedenbaan case.
