Congestion: what are Christchurch's worst offending roads?

As part of their mandate to "get the greatest efficiency out of the existing roading network", the Christchurch Transport Operations Centre installed Bluetooth sensors throughout the strategic road network in 2013. As well as providing real-time data for a host of operational uses, the data from these sensors have been monitored on a monthly basis to get a better understanding of the city's congestion hotspots. The large volume of data necessitated the development of sophisticated analysis tools and geospatial systems to present the results in a useful way. The intention behind this project sits firmly in the "Smarter" theme of this conference. The Bluetooth sensors provide a vast amount of data about traffic congestion. The challenge of this project was developing methods of processing the data into meaningful information which can then contribute to smarter decisions being made about the transport network. Results from July 2014 revealed that the roads with the highest costs of congestion were Fitzgerald Avenue, Brougham Street, Blenheim Road and Bealey Avenue, with congestion costs ranging from $140 - $1,700 per km/hr. The total cost of peak hour congestion for the monitored routes was calculated as $54 million per year. This paper describes the tools developed to monitor congestion in Christchurch, and presents further details of Christchurch's most congested roads, how bad they are and how much they are costing society.
