I want to calculate the lateral shifting / lane changing behaviour of vehicle in a traffic stream. I want to know about some methods by which practically this distance can be calculated on road?
Dear Malaya, I can think of two approaches basically: FROM OUTSIDE (video recording vehicles and video-analyzing distance/changes) or FROM INSIDE (naturalistic study with GPS location changes) related to centreline. But these are just my ideas. I am sure you can find several past studies, where you can check what methodology they used. Just one quick link - http://trid.trb.org/view.aspx?id=743236
You are advised to read the procedures adopted for data collection and analysis in following two studies by Indiana Department of Transportation, USA:
1. Truck travel characteristics as Indicator of System Condition and Performance
10.5703/1288284314627
1. 2009 TACT Project - Ticketing Aggressive Cars and Trucks
That combination of 3-axies accelerometer and 3-axies gyroscope.
Hi,
in our instrumented car, we have a video sensor installed from a company called mobileeye (www.mobileye.com/). They sell the system to reserach institutes with an extended interface so that you can get the raw measurement data, which is among others lateral and longitudinal distance to several objects ahead. so you can use this to measure the lateral movement of a car realtive to your car, what could be an additional way to get information about lane change behaviour.
