Pedestrian crashes in Bangalore: Part 2
Bangalore recorded 276 fatal pedestrian crashes in 2017, leading to 282 fatalities and 1332 injuries. As discussed in the previous blog, a majority of these crashes happened in the peripheral areas of the city.
To identify the key causal factors, it would be important to know when these crashes happened and how they are distributed across months, days-of-the-week, and time of the day. A month-wise analysis shows that nearly 14% of all fatal pedestrian crashes in 2017 happened in the month of January, whereas the crashes were comparatively low during the months of April and November. A significant 19% of all fatal crashes happened on Mondays as compared to 12% on Sundays. Interestingly, 44% of all crashes that happened in the month of October happened on Mondays.

An hour-wise analysis of crashes reveals that the crashes peaked between 6 pm and 10 pm. The second peak was observed between 5 am and 6 am. It may be useful to note that both of these peak periods correspond to poorly lit conditions. While 40% of all the fatal crashes happened during these windows, the highest number of crashes happened between 7 pm and 8 pm.
The crashes were very low in numbers from 1 am to 5 am; this is probably due to low vehicular and pedestrian volumes during this time. Intriguingly, the hourly crashes increased drastically by almost three times between 4-5 am and 5-6 am. This may be because pedestrian trips see a peak during this time as people get out for morning walks. The fact that speeds are largely unregulated during these times as a result of amber traffic lights increases the probability of high-severity pedestrian crashes.

The peak periods of crashes also varied depending on the day of the week, possibly pointing to varying pedestrian volumes and trip patterns across the city during different days of the week. The crashes were evidently high on Mondays between 8 pm and 10 pm, on Wednesdays between 7 pm and 8 pm, and on Saturdays between 5 am and 6 am. Further understanding of pedestrian trips during these specific hours is required to identify possible reasons for these crashes.

Further, an hour-wise and jurisdiction-wise distribution of pedestrian crashes shows that the peak crash periods varied among jurisdictions. While areas such as Electronic City, International Airport, VV Puram, KS Layout, Kamakshipalya, Wilson Garden, and Hulimavu saw high fatal crashes during early and late evenings, areas such as Yeshwantpur, HAL Airport, Upparpet, and Jayanagar saw high number of fatal crashes in the mornings. HSR Layout, Kengeri, and KR Puram had high crash periods during both during mornings and evenings.

This is the second of a four-part series that presents analyses from a pedestrian crash data study in the city of Bangalore. The study was based on FIR reports collected from the Bangalore Traffic Police for pedestrian crashes reported in the year 2017. The data was obtained through relevant RTI applications.
