Study of Impact of New High Rise Buildings on Road Traffic at Tardeo, Mumbai

Present Status and Progress

The project was taken with the basic objective of estimating the passenger / vehicular traffic generated by the proposed residential complex at Tardeo, Mumbai and assess the impact of this traffic on the adjoining road network.

Findings/Conclusions
For understanding the transport flows, the entire Mumbai Metropolitan Region (MMR) has been included and the region has been divided in to smaller areas called traffic zones. However, as this study primarily focuses on assessment of travel pattern due to the proposed residential complex in the southern portion of the Mumbai Island area (i.e. meaning thereby a study conducted at macro level) it has been decided to aggregate the identified zones from the previous studies (CRRI, 1983 and 1999) for the purpose of this study. Therefore, the zoning system adopted is confined to 13 zones only. The household travel study is primarily focused on estimating the total potential trips that would be generated from the proposed residential complex at Tardeo and would incorporate the data on travel by the residents of the building, the service personnel serving the residents as well as the visitors to the residents. The study involve household survey amongst a selected sample of households who possess similar socio-economic characteristics as that of the proposed complex in the vicinity of the study area by adopting carefully designed household travel survey proforma to elicit the information on the household size, socio-economic profile of members, travel made by individual members, income and expenditure on travel etc. The socio-economic characteristics data reflected the level of vehicle ownership, number of trips performed and usage of different modes. The essential requirement envisaged in this study is the estimation of impact on road traffic and changes in the travel characteristics which are likely to occur due to the proposed residential complex. The travel pattern established using the above household survey is expected to form an essential input to derive the estimation of modal share of the proposed residential complex. Since the residential complex is still in the development stage, it is considered appropriate not only to use the existing traffic data and the growth factors to estimate the traffic for the horizon year but also to develop a macro level transport model using TRIPS Software which would thus incorporate the future developments in estimating the travel pattern and modal share. The socio-economic characteristics, travel information of the household and other parameters like Per Capita Trip Rate (PCTR) collected as a part of this study has been used as the base to arrive at travel pattern and modal share which is likely to be generated due to the proposed residential complex. Subsequently, the base year and horizon year travel demand has been estimated due to the proposed residential complex at Tardeo by appropriately simulating them through modeling approach by using the TRIPS software.
Considering the future projected traffic expected to be generated from the proposed residential complex it is felt essential to provide additional road connectivity in addition to the existing M.P. Mill Compound road by connecting the proposed residential complex with the major road links. The best option which could be explored is by providing additional road connectivity directly from the proposed residential complex via M.L. Dahanukar Marg. The construction of this new road link would thus facilitate the road traffic emerging from the proposed residential complex to use the relatively less congested Pedder Road and N.S. Patkar Marg and thus act as an alternative road link (in addition to Tardeo Road) for the distribution of traffic towards the island and suburbs of the city through Pedder Road and N.S. Patkar Marg respectively.

Significance / Utilization Potential

The study output is expected to help the concerned authorities in assessing the magnitude of traffic that could be generated due to the proposed development and thereby take appropriate measures for capacity augmentation for the adjoining road network.
