Hyderabad: A research carried out by a city-based engineer has found eight dangerous stretches in Cyberabad, where more than 200 fatal accidents had occurred in 2017-18. The researcher, Mr Zubair Khan, found that these accidents took place on the stretches from Chandanagar to Miyapur, Gachibowli to KPHB, Jeedimetla to Medchal, Meerpet to Ibrahimpatn-am, Meerpet to Vanasthalipuram, Narsingi-Nanakramguda road, NH7 road towards Shamshabad, and Sagar Ring road to Rajendranagar have witnessed more than 200 fatal accidents.
Mr Khan, a student of road transportation engineering, developed an interactive model for identification of individual risk by using a Geographical Information System (GIS) software on the regional road network. His paper has been published in the International Journal of Technical Innovation in Modern Engineering and Science.
Mr Khan said he first identified the location of the accident and the road network by using Google Earth and imported accident data for 2017 on the ArcGIS software. The software identified the accident spots at Medchal, Dundigal, Miyapur, Keesara, Uppal, Adibatla, KPHB, Shamshabad, Narsingi, LB Nagar and other areas and categorised them into low, medium and high intensity according to data.
“The reasons for accidents may vary like drunk driving, road conditions like potholes, speeding, bad infrastructure or others,” he said. Using GIS, researchers can exhibit hazard positioning in a viable way and better convey the dangers, he said. “With access to data on accidents and traffic we can calculate the risk which will help identify safety levels.”
Asked about the finding, Prof. Laxman Rao of JNTU said, “It is a statistical analysis. It gives only a static version of risk analysis. For instance, a road median is not visible on Google. If it is visible, they couldn’t find the dimensions. Vehicle technology characteristics, driver's reaction, static deficiency and geometric fitness of the road al matter. The main reason for many of the accidents was the driver’s reaction and vehicle technology. Only by using a technology interface can we have a dynamic analysis”.
Mr M. Rakesh, who works on GIS, in a private company said, it was helpful in road mapping and designing. “If we are careful on these aspects, the risk of road accidents will be reduced.” He said by way of an example that L-turns, which are more risky, could be avoided.
