Gestió ambiental del trànsit. Un anàlisi conceptual.
Autors:Soriguera, F.
Congrés: III Jornades sobre ITS a Catalunya.
Lloc i Data: Barcelona, 22 - 26 de junio de 2009
Idioma: castellà
Resum:
En aquesta ponència es presenten les mesures prosades que proporciona la enginyeria de trànsit per compendre la gestió i estreure una opinió fundada.
Les mesures propostes son les següents:
- Assignació de carrils a un ús espcífic.
- Carrils Bus-VAO dinàmics: Incrementar l’ocupació dels carrils Bus-VAO en colls d’ampolla.
- Control d’accés diferencial segons destí.
- Gestió dinàmica de sortides: Evitar el col•lapse total de sortides amb un increment no habitual de demanda.
- Evitar el “gridlock”: evitar que tapin sortides molt demandades.
- Gestió variable del límit de velocitat.
- Desviació del trànsit entrant: redireccionar els vehicles que voldrien entrar just abans del coll d’ampolla congestionat a entrades aigües avall.
- Ús dinàmic del voral: Augmentar la capacitat de colls d’ampolla puntuals i recurrents; i desbloquejar sortides (OD consecutius).
- Resposta ràpida en cas d’incidència: reduir la durada de les incidències, grues circulant en zones d’elevada densitat d’incidències, aïllar l’incidència i evitar l’espectacle.
- Gestió de la demanda: prohibició / regulació de l’accés, tarificació de l’accés, carrils exclusius.
Les idees s’han d’aplicar fent un ús adequat de les noves tecnològies.

CITYSOLVER: Una proposta de sistema integrat ATIS-ATMS basat en aplicacions TIC.

Resum:
Since the inception of Intelligent Traffic Information Systems (ITS), Advanced Traffic Information Systems and Active Traffic Management Systems have been considered the main ITS paradigms where considerable resources and effort has been spent closing the gap between theoretical concepts and systems working in practice. However, none of the existing systems, with a few exceptions of systems based on specific technologies and substantial public support or addressing specific scenarios (e.g. VICS, EASYWAY, WISETRIP, IN-TIME etc.), can be considered fully satisfactory and most commercial systems based on private initiatives are far from providing the expected reliability. Navigation systems are pervasively penetrating the market but are still massively used on the basis of static information, semi-dynamic in the best cases, or statistical information based on the exploitation of data uploaded from subscribers (e.g. Tom-Tom Map Share, IQ Routes). These are still far from the achievements envisaged by theoretical conceptions of dynamic navigation systems. In a similar way concerning Active Traffic Management Systems (ATMS), most of the current systems are operating in Highways and Motorways while in urban areas only a few systems have been partially implemented subject to certain limitations. The pervasive penetration of ICT Applications enables gathering traffic data from multiple data sources (e.g. loop detectors, cameras, floating car data, detection of mobile devices, ETCS, etc.), filtering and integrating data in a coherent, consistent data set, inputting to traffic models that after suitable processing transform the data into information supporting both the ATIS and traffic managers responsible for the Active Traffic Management System.
CITYSOLVER proposes the architecture of an ATIS application as an Advanced Journey Planner that is able to present travellers in real-time, interactively, and by means of currently available “off-the-shelf” technologies, information on alternative modes of transit to assist their decisions at the pre-trip as well as at the in-trip stages. CITYSOLVER also includes in its architecture ATMS applications enabling efficient and effective traffic management in real-time, based on a real-time estimation of the traffic network state, to support adaptive road access while advising drivers and other road userson recommended courses of action. This presentation describes the integration and data fusion techniques to fully esploit the available data, the dynamic traffic models completing the missing information and the means to efficiently disseminate and exploit it to support ATIS-ATMS functions.
