The impact of intelligent vehicles on a two-route system with a work zone

Abstract

By the cellular automaton (CA) model, tra±c behaviors of an intelligent two-route system with a work zone are studied. In the model, the two-route system consists of a double-lane (DL) and a single-lane (SL). Supposing a work zone exists on DL, a big tra±c jam will be formed. For improving the system tra±c°ow, an intelligent vehicle (IV) which can change driving strategy on the basis of received real-time information has been introduced into the model. The simulation results indicate that the tra±c condition can be improved and the area of the tra±c jam can be reduced e®ectively if there are enough IVs. Moreover, if all of the vehicles are IVs, the tra±c jam may disappear, and the system will be in free°ow state.

Solution of jamming transition problem using adomian decomposition method

“…Traffic jam is a microscopic phenomenon for which some researchers have focused on the jamming transition problem (JTP) in its various forms (Nagel, 1994; Nagatani, 1998, 2000, 2002; Ben-Naim and Krapivsky, 1999; Maerivoet and De Moor, 2005; Peng et al , 2012; Gupta and Redhu, 2013, 2014; Xiao et al , 2017). The problem has been considered using thermodynamic (Nagatani, 1998; Ge et al , 2015), hydrodynamic and kinetic theories (Nagel, 1994; Peng et al , 2011), based on the car-following model (Tang et al , 2009; Gupta and Redhu, 2013; Yang et al , 2013; Qian et al , 2017a; Li et al , 2017), Maxell model (Ben-Naim and Krapivsky, 1999) and cellular automaton model (Maerivoet and De Moor, 2005; Qian et al , 2017b; Xiao et al , 2017). There are also some works available transforming JTP into a nonlinear oscillator with a restoring damping term, via the Lorenz system (Ganji et al , 2011, 2012; Han et al , 2013).…”
