MACROSCOPIC MODELLING OF PLANNED PEDESTRIAN FACILITIES

Abstract

India is the second most populated country in the world with its population more than one billion.The Tremendous growth of population had gave forth a huge demand for infrastructure, which is beyond the reach of governmental agencies due to resource crunch. In every year higher than 130 survives are being vanished in Chandigarh city in India Based on traffic condition and physical characteristics of road the data is collected for four locations of Chandigarh using video survey method on the sidewalk. The data collection is divided in each interval of 30 seconds. The data is collected using video survey method for one hour duration. A longitudinal trap lenght of 10 in is made on the road for measurement of flow and speed by white tape. These locations are PCI hospital. Punjab University. Sukhna Lake and Rose garden. The pedestrian flow characteristics are observed for all the study locations. Free Flow speed varies from 70.48m/min (l.17m/s) to 84.0 14m/min (1.4m/s) at all the locations of Chandigarh. Maximum Free Flow speed is found at PGI Hospital and minimum is found at Sukhna Lake. Jam density at all the locations of Chandigarh for sidewalk varies from 6.045 to 1.26 ped/m2.The maximum jam density is found at PCI Hospital and minimum is found at Rose garden. Flow rate is found varying from 126.96 to 24.36 ped/m/min. Maximum flow rate is observed at PGI Hospital and minimum flow rate is observed at rose garden. Optimum space value at maximum flow rate is found varying from 0.33 to 1.58 m2/ped. The Average speeds of pedestrians are found to be 67.95m/min for the sidewalks of Chandigarh for all type of land use. It is found that childrens in the group of age of 10 to 15 years having walk with average speed of 71.69 in/min( 1 .1 9m/s).Pedestrian in the age group of 15 to 60 walk with average speed of 69.8 m/min (1.16m/s). Otder pedestrians in the age group of above 60 years walk with mean speed of 62.33m/min (1.03m/s). analysis it is found that male pedestrian walks with average speed of 72.8 rn/mm (1.21m/s) while female pedestrian walks with average speed of 63.1 m/min( 1.05m/s).The reduction in the speed value is around 13 percent. The level of service criteria based on the space available as given by present study is slightly more than the criteria all the compared criteria but less than that given by HCM (2010). The level of service criteria based on flow is less than the criteria given by all the compared criteria.
