Data collection and analysis of macroscopic real-time urban traffic flow

摘要

The study has been conducted on the small real world area of JNU where the traffic trends were monitored manually. One month data has been taken into consideration for analyzing the macroscopic traffic flow of JNU. The traffic patterns were observed from the four different entrance/exist gates. In this, the realistic car mobility covering one month, 24 hour traffic in a span of 1019.38 acres region has been analyzed. Further, the real world behavior such as low traffic at night and high peak Incoming traffic at around 9:00 AM and outgoing at around 5:00 PM, excluding weekends, has been observed. The density and speed was calculated by the given flow of vehicular traffic. Later, the realization of traffic stream model i.e. flow-density relation was discussed. In this, the importance of scaling factor in case of less data availability came into picture.
