Abstract

This paper presents the modelisation exercise based on the Madrid HOV lane as part of the ICARO project, which in turn is part of the IV EU Framework Programme RTD. ICARO's main goal is to look into ways of increasing car occupancy. Since its opening in 1995, the Madrid's HOV lane has had a big impact on commuter demand for the N-VI radial corridor. The present cut off limit stands at 2+. However, in the light of the upward trend in mobility rates expected to take place in the corridor, traffic conditions will have reached stalemate in about 7 to 10 years. This result stands out as particularly significant in a corridor where environmental and land use availability hamper considerably any attempt to increase road capacity.

One of the possible solutions to prevent congestion in the HOV lane is to rise the minimum requirement up to 3+. In view of the relevance of these aspects, this paper has been conceived to deal with the medium and long-term impact resulting from this option. The results provided in this paper were obtained through a model built on specific SP surveys taken to current HOV users. Results revealed the great potential of the HOV lane limit in the managing of the N-VI corridor.
