Travel-time surveys have long been used to provide performance data for the assessment of traffic systems. The traditional methods of finding the amount of travel time have been difficult to apply. With the advent of the Global Positioning System (GPS) a new era in transport data collection has arrived. Not only will it benefit data collection in travel-time surveys but other areas dealing with transportation issues will also gain, eg road asset management Intelligent Vehicle Highway Systems and real-time vehicle tracking among others. The GPS-GIS combination forms an effective partnership in that the GPS system allows the efficient collection of data, while the GIS provides an interface that allows these data to be displayed together with their spatial attributes.
