Implementation Roadmap for Sustainable Urban Freight Mobility in Chennai -2020
Figure 18: Freight vehicle parking duration
It can be observed that in all the three stretches, most freight vehicles were parked for 10 mins or less. On average, 50% of freight vehicles were found to be parking for less than or equal to 20 minutes. This data was utilized in simulation, which will be discussed in the latter part of this report.
4.4 Parking Plan using VISSIM In this section, traffic simulation performed to evaluate the current parking practices, including double parking of freight vehicles and the results obtained, are discussed. A scenario with proposed dedicated freight parking spaces is simulated, and the results are compared to double parking case.
Network, Input data and Calibration: Sir Theagaraya road was 4-lane divided carriageway with two lanes for each directional traffic. Pondy Bazar, which is part of Sir Theagaraya road, underwent modifications under a Smart City project called ‘Pedestrian Plaza’ project. Pedestrianization of Pondy Bazar ensured comfortable walking with wider footpaths, thereby reducing the carriageway to 3.5m for each direction of traffic (total carriageway width 7m). Due to the reduction in carriageway width, concerned authorities limited the traffic movement on Sir Theagaraya road to uni-directional traffic (one-way) from Panagal park to Thanikachalam road junction. These modifications were adopted in the simulation.
