2011 - India - Effect of Geometry on Road Capacity

The knowledge of roadway capacity is an important basic input required for planning, analysis and operation of roadway systems. Expressing capacity as number of vehicles passing a given section of road or traffic lane per unit time will be inappropriate when several types of vehicles with widely varying static and dynamic characteristics are comprised in the traffic. The problem of measuring volume of such heterogeneous taffic has been addressed by converting the different types of vehicles into equivalent passenger cars and expressing the volume in terms of Passenger

Car Unit (PCU) per hour. The effect of variation of traffic volume, road width, magnitude of upgrade and its length on PCU value is studied. A recently developed heterogeneous traffic-flow simulation model, named, HETEROSIM is used for this study. Field data collected on traffic flow characteristics are used in calibration and validation of the simulation model. The validated simulation model is then used to derive PCU values for different types of vehicles. The PCU estimates, made through microscopic simulation, for the different types of vehicles of heterogeneous traffic, for a wide range of traffic volume and roadway conditions indicate that the PCU value of a vehicle significantly changes with change in traffic volume, width of roadway, magnitude of upgrade and its length. Using the derived PCU values, capacity guidelines are also developed for typical roadway and traffic conditions.

Chris in the NCT Race 

Chris has an adventurous spirit which generally involves cycling, running, or just being out there having a good time. Read his 'Race Reports' below. This is a link to his SPOT GPS tracker. If you are interested in his 'geeky' sport technical blog it is at www.tri-duffer.com. He also has stories of his life as 'An Overtravelled Engineer Working for the World Bank' at World Bank Traveller.

Chris and Lis

We are Lis Pedersen and Chris Bennett. We’ve been married over 30 years and each found our way to New Zealand in the early 1980s from Denmark and Canada respectively. Golden Bay has been our happy place for almost 20 years and we are now based in Pohara just above the beach, with our two cats Coco and Max.
