The Signalling System may be upgraded to allow the trains at closure headways. Supply side measures for urban transport. DMRC has progressively increased the number of cars per train from 4 cars to 8 Cars now at Line 2, Line 3 & 4.įigure 1. The carrying capacity can also be increased by adding more cars per train even without increasing the number of trains provided system permits addition of more cars. The carrying capacity can be simply increased by introducing more trains in an hour if system permits. The carrying capacity of a URT system is determined by passenger capacity of the trains passing through a point in an hour. The capacity offered may be enhanced by deploying the following measures individually or in combination. The supply management tools deployed in URT are listed Figure 1 below. The supply management tools are applied incrementally to match the increasing demand over the time. However, the increase of supply is limited by the design capacity of the system beyond which any increase in the supply requires major investment to enhance the capacity of the system. Improvement in services spurs the growth of the transport demand. The supply side measures refer to transit service quality factors such as availability, convenience, speed and comfort. The additional capacity not only addresses the peak hour congestion but also attracts new traffic as people find it easier to use services with additional capacity. The measures to increase the supply are termed as Supply Side Measures to meet the demand. Conventionally more capacity in terms of number of vehicles per hour is offered in the peak hours to meet the demand. The peak hour demand in Urban Rail Transport is usually significantly higher than the demand in nonpeak hours. An optimum combination of supply and demand side measures would perhaps be the best way to address peak hour congestion in Urban Rail Transport.Ĭongestion, Demand, Elasticity, Supply, Urban Rail Transport The efficacy of supply side measures is limited by the design capacity of the system beyond which any increase in supply would require disproportionate investment. The model has been applied to Line 2 (yellow line), the busiest line of DMRC, to estimate the demand for different level of services (trains/hour). A simple service elasticity model has been developed to estimate demand with increase in supply. So a 10% increase in supply results into 5% increase in capacity. The demand elasticity w.r.t services for the passengers of DMRC has been estimated as 0.512 on the basis of growth of demand and increase in capacity after adjusting for natural growth. The ridership of the system has also witnessed double digit growth during this conversion period. Delhi Metro Rail Corporation (DMRC), India has converted its fleet from 4 cars per train to 6 cars per train and finally to 8 cars per train on its Broad Gauge section. This additional capacity generates more demand due to a positive elasticity of demand with respect to services.

The high peak hour demand in Urban Rail Transport (URT) is usually met by supply side measures such as pushing more number of trains/cars in peak hour by the operator. Received 9 February 2016 accepted 27 June 2016 published 30 June 2016
