“…This simplification is also consistent with the store-andforward modeling approach [16]. The oscillatory behavior of the system, induced by the traffic lights, is lost and the vehicles entering or leaving the section may be seen as a continuous flow passing through a bottleneck, as long as demand and supply functions of upstream and downstream cells are capacious enough.…”

“…In other words, the earlier the vehicles are able to exit the network (by appropriate use of the available control measures) the smaller TTT will be [16]. It is also important to notice that if reducing v f does not induce a reduction of the inflow, the only effect would be a redistribution of the vehicles inside the road section, the average number of vehicles would not change and the TTT would not be affected.…”

Abstract-The problem of traveling at maximum energy efficiency (Eco-Driving) is addressed for urban traffic networks at macroscopic level. The scope of this paper is the analysis of the steady-state behavior of the system, given certain boundary flows conditions fixed by traffic lights timings, and in presence of a traffic control policy based on variable speed limits. The formal study is carried out on a two-cells variable length model adapted to the urban setup from previous works on highway traffic [1] [2]. Informative traffic metrics, aimed at assessing traffic and vehicles performance in terms of traveling time, infrastructure utilization and energy consumption, are then defined and adapted to the new macroscopic traffic model. If congestion in a road section does not spill back or vanish, the system is stable and many different equilibrium points can be reached via variable speed limits. Efficient operation points and traffic conditions are identified as a trade-off between optimization of global traffic energy consumption, traveling time and infrastructure utilization.

The paper focuses on the simulation of signal control problems based on VISSIM microscopic simulator. VISSIM is a commonly used software in practice for diverse problems related to road traffic control. Beyond the standard use of VISSIM, advanced options are available. VISSIM COM interface and VISSIM DLL API may be used as well providing freedom to the traffic engineer. By exploiting the programming possibilities efficient simulations may be achieved. As additional possibility MATLAB may be involved in the traffic simulation as well creating an integrated environment with VISSIM. Thus, complex mathematical problems can be calculated online by MATLAB and used for VISSIM simulation.The work is connected to the scientific program of the "Development of quality-oriented and harmonized R+D+I strategy and functional model at BME" project.
