Modeling framework for optimal evacuation of large-scale crowded pedestrian facilities

Abdelghany, Ahmed; Abdelghany, Khaled; Mahmassani, Hani; … - In: European Journal of Operational Research 237 (2014) 3, pp. 1105-1118

The paper presents a simulation–optimization modeling framework for the evacuation of large-scale pedestrian facilities with multiple exit gates. The framework integrates a genetic algorithm (GA) and a microscopic pedestrian simulation–assignment model. The GA searches for the optimal...

Energy dissipation of traffic flow at an on-ramp

Xue, Yu; Kang, San-Jun; Lu, Wei-Zhen; He, Hong-Di - In: Physica A: Statistical Mechanics and its Applications 398 (2014) C, pp. 172-178

This paper proposes a new cellular automaton traffic model to study the energy dissipation in an on-ramp traffic system. Different from previous works, we investigate not only the traffic behavior in on-ramp flow system, but also the variation of energy dissipation in it. The numerical...

A new proposal for analyzing combustion process stability based on the Hamming distance

Souza, J.W.G.; Pereira, H.B.B.; Santos, A.A.B.; Senna, V.; … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 301-306

In this paper, the concentration of soot during controlled combustion is analyzed using two fuels: acetylene (AC) and natural gas (NG). The stability was evaluated within the spatio-temporal standards generated by the system evolution, which was based on the measuring technique known as the...

Simulation study of traffic car accidents in single-lane highway

Bentaleb, Khalid; Lakouari, Noureddine; Marzoug, Rachid; … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 473-480

In this paper we numerically study the probability Pac of the occurrence of car accidents in the extended Nagel–Schreckenberg (NS) model in the case of mixture of fast (Vmax1=5) and slow vehicles (Vmax2=1) by taking also to the risky overtaking of fast vehicles. In comparison with previous...

Network formation by contact arrested propagation

Hafver, Andreas; Jettestuen, Espen; Baetens, Jan M.; … - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 240-255

We propose here a network growth model which we term Contact Arrested Propagation (CAP). One representation of the CAP model comprises a set of two-dimensional line segments on a lattice, propagating independently at constant speed in both directions until they collide. The generic form of the...
