Short time scientific missions
Name, Surname: Alfonso Bahillo
Organisation: DeustoTech – University of Deusto
Grant: José Castillejo for young researchers (Spanish Ministry of Education, Culture and Sport)
Stay period: from 01.09.2016 to 01.12.2016
Research area: Smart mobility
Short description of the research area: In this research, we place the increasing penetration of digital technologies devices (smart phones, smart watches, tablets, etc.) within the broader context of their use in public spaces, not only open spaces such as parks, gardens or plazas but also closed such as train stations, museums, hospitals or city-malls. The consequences of this interweaving, which are growing at a rapid pace, are not yet fully investigated. This fact accompanied by their rapid development and increasing application possibilities, challenges urban planners, social scientists and ICT experts.

Transport modelling and traffic simulation
Short description of the research area:
The research area encompass analysis and modelling of Park and Ride system at macro/city level. This consist of application of travel demand modelling tools (PTV VISUM) in order to estimate potential operation of proposed Park and Ride sites and identification of optimal Park and Ride locations.

Grand: COST TU 1004
Stay period: 14/10/2013 to 1/11/2013
Research area: Transport and emission modelling
Short description of the research area: The research during the stay has been focused on the calibration and simulation of transport models in Madrid and Riga.
The case study in Madrid corresponds to a section of the M-30 ring motorway which is normally used by buses coming from North Spain and accessing to the main bus station in Madrid. In this section, a variable speed limit system have been put into operation in last month.
This research tries to find how this ITS influence the traffic performance and how this could affect the assignment in the macro model. The first step carried out during this STSM has been to program a script which simulates the effects of VSL in an already existing traffic micro model (VISSIM).
After that, we have studied how to link the VISSIM outputs with the VISUM macro model. Speed-Intensity curves have been analysed in order to obtain data to adjust the volume-delay functions (VDF) in VISUM, which will influence in the assignment model.
Procedures to calibrate both models have been discussed, analysing also literature provided by TTI colleagues.
In the framework of these case studies simulations, EnViVer software was also used in order to analyses VISSIM output and provide information about emissions and air quality.
