TRANSPORTATION AND COMMUTING5.2 Traffic congestion and itssocio-economic costsRising congestion costs estimated at$1.4 billion in 2003During the AM and PM peak hours, a considerable portionof Greater Montréal’s road and highway system experiencesrecurring congestion problems, in all five geographicsectors. 14 Between 1998 and 2003, related costs jumped50%, mainly as a result of the higher numbers of automobilestravelling in the area.The most recent research on traffic congestion in themetropolitain area, which was conducted by TransportQuébec in 2009, estimates that 27% of the trips madeduring morning rush hour in 2003 were hampered bycongestion. For the Montréal agglomeration, the figure was41%; for Laval, 33%; for the Longueuil agglomeration, 25%Traffic congestion during morning rush hour(6:00 to 9:00 a.m.), 2003Vehicle-kilometres total and congested (in thousands)Geographic sector MontréalagglomerationTotal congested %Montréal agglomeration 6,200 2,540 41%Longueuil agglomeration(excluding Saint-Bruno-de- 1,900 480 25%Montarville)Laval 1,870 620 33%North Shore 3,390 450 13%South Shore 3,390 450 13%Greater Montréal 16,360 4,470 27%Source: Ministère des Transports du Québec (2009), Évaluation des coûts de lacongestion routière dans la région de Montréal pour les conditions de référence de 2003.Calculations by the CMM, 2010.(excluding Saint-Bruno-de-Montarville); and for the North and South Shores, 13% each. The estimated costs of such congestionstood at $1.4 billion in 2003, $1.2 billion of which were delay related (i.e., time lost). Other costs can be broken down into fourcategories: vehicle usage ($114 million), fuel ($40 million), polluting emissions ($15 million) and greenhouse gases ($8 million).Socio-economic costs attributable to recurring highway and road congestion, 2003 and 1998(millions of 2003 dollars)44Geographic sectorMontréalagglomerationDelays2003Vehicle-usage costs(excluding fuel)2003Fuel costs2003Pollutingemissions2003Greenhousegas emissions2003Total costto society2003Total costto society1998Total costto society2003same methodas for 1998753.0 68.0 23.8 8.9 4.9 858.6 - -Variation (%)Longueuil agglomeration(excluding Saint-Bruno-de-Montarville)174.0 14.0 5.0 2.0 1.0 196.0 - -Laval 164.0 16.0 5.4 2.0 1.1 188.5 - -North Shore 76.0 8.0 2.8 1.0 0.6 88.4 - -South Shore 79.0 8.0 3.0 1.2 0.6 91.8 - -Greater Montréal 1,246.0 114.0 39.9 15.0 8.1 1,423.0 841.0 1,263.6 50.3%Source: Ministère des Transports du Québec (2009), Évaluation des coûts de la congestion routière dans la région de Montréal pour les conditions de référence de 2003.Calculations by the CMM, 2010.14 The data presented in this section come from Transport Québec’s Évaluation des coûts de la congestion routière dans la région de Montréal pour les conditions de référencede 2003, published in 2009. In this study, the geographic boundaries of the North and South Shores are somewhat different than for their CMM counterparts, the maindifference being that, in the Transport Québec study, the North Shore includes the RCMs of Rivière-du-Nord and part of the Pays-d’en-Haut RCM, and the South Shorecomprises the entire area encompassed by the La Vallée-du-Richelieu RCMs (including the municipality of Saint-Jean-sur-Richelieu) and the municipality of Saint-Brunode-Montarville,which forms part of the Longueuil agglomeration.
