Linear programming model for estimating high-resolution freeway traffic states from vehicle identification and location data
H Lei, X Zhou - Transportation Research Record, 2014 - journals.sagepub.com
The estimation of traffic state on freeway segments is widely studied as a complex nonlinear
and stochastic estimation problem. A unified representation with a parsimonious explanation
for traffic observations under free-flow, congested, and dynamic transient conditions is
developed by capturing the essential characteristics of forward and backward wave
propagation through cumulative flow count variables. New formulations are presented to use
Bluetooth vehicle identification records and GPS vehicle location data on a freeway corridor …

ABSTRACT 1 Traffic state estimation on freeway segments is widely studied as a complex
non-linear and stochastic estimation 2 problem. By capturing the essential forward and
backward wave propagation characteristics through cumulative 3 flow count variables, this
