Intelligent Transport Systems
As a researcher Luis contributed to computer-assisted techniques for the design of roundabouts, bus priority schemes and the application of video image processing to traffic data collection and incident detection. He was involved in the application of Artificial Intelligence techniques to transport and in a number of European Community advanced research projects. He has a sound understanding of Urban Traffic Control Schemes, including the adaptation of programs such as TRANSYT and SCOOT to local conditions. He has experience in the specification and implementation of free-flow tolling and road-user charging technologies and their impact on the business case for ITS applications.

Congestion Charging in Edinburgh
Luis directed a review of the modelling system developed to study the impact of a possible congestion-charging scheme in Edinburgh. He produced a simplified version of the same to gain additional confidence in the results in order to build a business case for the scheme. The original model used, employed a simplified road network but a rich set of behavioural responses and a Land Use Transport interaction sub-model. The results produced were, however, very variable hence the need for a better grounded simplified model to support the decision-making process. This was delivered successfully on time. Later on, public consultation resulted in the charge being abandoned. . |

Research into modern sensors for traffic modelling
He has undertaken research into the use of modern sensors for traffic data collection and monitoring. This includes the use of personal (portable) GPS unit, mobile phone data, video imaging in addition to more conventional data sources. In the case of personal and portable GPS loggers they were provided to a sample of travellers to collect travel information over three days. This information can be used to complement travel diaries and gather data on underreporting of trips. The research was implemented in London, a very demanding environment for GPS, and the main focus was on public transport rather than car trips. Results were very encouraging as a complement and partial replacement for conventional surveys.

Procurement of Electronic Toll Collection for Puerto Rico
He acted in a supervisory role on this major exercise in specifying a new electronic toll collection system for the Island. During the, in initial stages a few toll lanes were implemented rolling out the programme to cover eventually the whole system. Issues of enforcement technology and legislation, technology reliability, Customer Service Centre and Clearinghouse Services were part of this assignment. |
