— The urban transit routing problem (UTRP) for public transport systems involves finding a set of efficient transit routes to meet customer demands. The UTRP is an NP-Hard, highly constrained, multi-objective problem, for which the evaluation of candidate route sets can prove both time consuming and challenging, with many potential solutions rejected on the(More)
The urban transit routing problem (UTRP) is NP-Hard and involves devising routes for public transport systems. It is a highly complex multiply constrained problem and the evaluation of candidate route sets can prove both time consuming and challenging, with many potential solutions rejected on the grounds of infeasibility. Due to the problem difficulty,(More)
—Low-carbon management is an important area of urban study and city management, and it is a critical element of the modern city system. Even though the importance of low-carbon management has been recognized, low-carbon problems are still salient and even worse than ever before in some developing countries, like China. Nowadays, "big data" techniques may(More)
An extension of the feedback local ramp metering strategy ALINEA is presented to realize early-warning for downstream ramp metering and timely adjust the ramp metering rater. The new metering algorithm needs to establish some detectors monitoring the maximum traffic volume. We develop an estimation of upstream maximum traffic volume. Simulation results show(More)
