Impact of Metro on Road Network and Road Transport Systems: A case study on Delhi

Duration:January 2004 to June 2004
School of Planning and Architecture, New Delhi (R)

Scope and Objective
The aim of the research is to determine the impact of metro on network and transport systems
(i) To appreciate the role and importance of MRTS in urban areas.
(ii) To review through literature search the impacts of MRTS on road network and road transport systems.
(iii) To assess the network and transport system characteristics on the case study metro corridor from Shahdara to Trinagar. (iv) To assess the impacts of metro on road network (capacity, speed, LOS), traffic (mix) and road transport system (Ridership       or patronage, load factor, fleet size and other productivity measures).
(v) To recommend policy guidelines for transport operations along metro corridors.

The aim of the study was identified which helped in establishing the need for the study after which the objectives were formulated. The Literature Review was carried out for the following three categories namely a) Impact Congestion – concepts and Measure, b) Studies on Transit corridor impacts c) Studies on diversion models. This helped in identifying the issues and identification of parameters to measure impact. After this data requirements were worked out. The sources of secondary data were identified and primary surveys were conducted. This helped in the impact assessment and formulation of guidelines for transport operations along Metro Corridor. This led to assessment of impact of Metro for proposed corridors.

Findings and Conclusions

(i) MRTS is a new concept especially in developing countries. Hence particularly in cities in which the expansion is going on,     such studies need to be conducted.
(ii) Literature review indicates that 60% of the studies dealt with landuse, land value, urban form and socio-economic impacts     and 40% dealt with network and transport system changes
(iii) Impact assessment approach adopted world wide includes a hierarchy of effects namely primary effects (changes in travel      patterns, changes in public transport network), secondary effects (effects on activity centers) and tertiary impacts (land      use changes, property values, job mobility)
(iv) Basic parameters to measure impact are public transport productivity (fleet size, load factor, turn around time, dwell time)      network productivity (speeds, delay, throughput at LOS “C”) and environment quality.
(v) Primary survey reveals that there have been significant improvement in speeds in the parallel arterial corridor (5-10%), but       the speeds in the network of the catchment area has decreased (0.19-3%)
(vi) Results from primary survey indicate that there is decrease in bus flow rate, bus passenger trips, av. Dwell time, turn       around time of the buses in both the parallel arterial corridor and other network in the catchment area
(vii) Model developed for the corridor indicates that for every 10%change in the station load, speed changes by .1%, bus flow       rate changes by .12%
(viii) Model developed for Shahdara –Trinagar corridor is validated on Trinagar –Rithala corridor within an error of 5-7%.
(ix) Model developed for Shahdara –Rithala corridor can be used for prediction of network productivity, public transport       productivity and environment quality of any corridor.
