Chennaites travel behaviour will be mapped using a new software by Chennai Unified Metropolitan Transport Authority (CUMTA) to prepare a revised transport roadmap for the city for the next 25 years.
Systra, the consultant appointed by CUMTA, will come out with a transport model which will integrate household activities, land use patterns, traffic flow, and regional demographics. The model would be able to estimate travel behaviour in response to economic conditions, network conditions and facilities, the residential and employment location, land use and adaptive behaviour in response to transportation system changes.
Sources said that the consultant would develop the 4-stage transport demand model using Vissum, one of the world's leading transport planning software. The travel demand model would be based on the data collated from primary surveys and secondary resources for the entire Chennai Metropolitan Area (5904km).
The software will be capable of multi-modal split, transit assignment, and assessing the variations in speeds and frequency due to changes in overall traffic volume, and fares. It should also reflect the impact of new land-use developments or control policies.
It is learnt that an inception report of revised comprehensive mobility plan, prepared by the consultant, was submitted to the government recently. Sources said that it will be reviewed by a high-level committee to work out other strategies. It is learnt that the revised CMP focusses on Green, Resilient, Inclusive, Development focused and Safe (GRIDS) principles focusing on the movement of ‘people’ instead of vehicles. The plan will look at mass transit options that will complement the proposed metro alignment. It could be another light rail system or a Bus Rapid Transit System, sources said.
BRTS, a dedicated lane for buses, was mooted nearly eight years ago but it never took off depite a detailed project report for five corridors was taken up. Compared to all other proposed transportation networks, BRTS costs the least, as it does not require commissioning of crores worth new infrastructure. Experts believe that the system could help increase patronage of public transport from the present 27 per cent to 40 per cent.
Apart from that the CMP is also looking at Metro Lite, an upgraded tram like mode. Metrolite, which will cost around 40-50 per cent of Metro Rail System, could link metro rail corridors under Phase I and Phase II which are five to six kilometres apart. The Comprehensive Mobility Plan is being revised after the final draft was finalised in February 2020 during an authority meeting of Chennai Metropolitan Development Authority.
