At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...

This paper suggests an effective approach to design optimal strategic air traffic management strategies under weather uncertainty. The approach is based on the multivariate probabilistic collocation method, which constructs a good low-order polynomial approximation of the original system mapping over likely parameter values, from which optimal management strategies can be derived. We illustrate...

The increasing demand for high capacity in cellular networks requires huge energy consumption. Thus, energy efficiency is becoming a vital design goal in cellular networks. We consider energy efficient base station sleeping and clustering problems in cooperative cellular networks where clusters of base stations jointly transmit to users. Our key idea of energy saving is to exploit a spatio-temp...

Traffic and Patrol Police Service Platforms in short, TPPSP in the city have been playing an important role in dealing with emergency and traffic administration. The national college mathematical modeling contest of China in 2011 proposed the problem related to the optimal dispatch of TPPSP. However, only the case without any traffic congestion is considered for the problem. It is well known th...

This paper presents a feedback control design for a coordinated ramp metering problem. We design an optimal traffic allocation scheme for ramps based on Godunov’s numerical method and using distributed-diffusive model. Most of the previous work for designing feedback control for ramp metering is based on either the discretized linear methods such as ALINEA or nonlinear methods based on the traf...

The robustness and integrity of IP networks require efficient tools for traffic monitoring and analysis, which scale well with traffic volume and network size. We address the problem of optimal large-scale flow monitoring of computer networks under resource constraints. We propose a stochastic optimization framework where traffic measurements are done by exploiting the spatial (across network l...

We consider energy efficient base station sleeping and clustering problems in cooperative cellular networks where clusters of base stations jointly transmit to users. Our key idea of energy saving is to exploit a spatio-temporal fluctuation of traffic demand, which is to use minimal energy to provide capacity only slightly greater than varying traffic demand. Then, energy saving is possible wit...
