Disaggregate models aggregate data Two UrbanSim applications
2010/10/25
UrbanSim has significant data requirements. In particular, it requires disaggregate data (traditionally at the 150 meter by 150 meter gridcell level) for employment, households, and buildings. While s...
Prediction Model of Bus Arrival and Departure Times Using AVL and APC Data
Prediction Model Bus Arrival Departure Times AVL APC Data
2009/10/19
The emphasis of this research effort was on using AVL and APC dynamic data to
develop a bus travel time model capable of providing real-time information on bus
arrival and departure times to passeng...
Bus transit operations are influenced by stochastic variations in a number of factors
(e.g., traffic congestion, ridership, intersection delays, and weather conditions) that
can force buses to devia...
