SELECTION SUMMARY
도입 판단 요약
Traffic data comes from sensors installed at city intersections. These sensors do not take video of traffic, but instead determine by size whether each passing vehicle is a car, truck, bike, van, etc. The table below shows traffic at each intersection in 15-minute increments. This data set is grouped by directionality; each row is a sum of all the vehicles of a specific type that entered and exited the intersection in the same directions during the same 15-minute time window. To see this data grouped together further (by vehicle type, intersection, and time, disregarding directionality), see https://data.cambridgema.gov/Traffic-Parking-and-Transportation/resource/sqpt-e4ih) This dataset contains counts for different kinds of vehicles. For pedestrian counts, see https://data.cambridgema.gov/Transportation/MioVision-Daily-Pedestrian-Counts/7zcp-kyfg/about_data. When a sensor is offline or being repaired, some data may be incomplete or missing.
