Despite the documented benefits of ride-sourcing services, recent studies show that they can slow down traffic in the densest cities significantly. To implement congestion pricing policies upon those vehicles, regulators need to estimate how much their congestion effects are. This paper studies...

Purpose: To develop LIRP (location-inventory-routing problem) model with considering multiple links and solve it using method of heuristic based on algorithm of simulated annealing. Method of heuristic for the LIRP model is applied in city of Jakarta to improve effectiveness and efficiency of...

Like most others, traffic economists also treat a vertical line for the capacity of a road. When traffic flow approaches the vertical line, there will be congestion, while the line itself is a gridlock. This paper re-runs the traffic mathematics thoroughly, to derive some surprisingly new...
