Steps to reproduce

• The trajectory data is from an urban midblock road section on Dumas road in Surat, India. For a trap length of about 600m and width 10.5m (3 lanes of each 3.5m). • Considering a foot-over -bridge as a vantage point, four wide-angle digital cameras were installed and focused at four different continuous road segments with trap lengths of 230m, 120m, 100m, and 75m, respectively. • It covers an entire extended study stretch of 535m for developing high-quality trajectory using continuously captured data on vehicular movement over space and time. • Vehicular trajectory data were developed individually over the four segments with an update interval of 0.5sec, by tracking vehicles for each of the four segments separately. • Further, based on the stitching algorithm, a continuous trajectory was developed. Overall including miss-stitches and unstitches, the data is about 85 per cent accurate. • The trajectory data contains about 591 vehicles for 20 minutes.
