Emissions by road traffic can be reduced by optimising traffic control. The impact of this optimisation on emission can be analysed ex ante by simulation. The simulation programs used for this analysis should be valid with respect to the traffic characteristics that determine the emissions. Thus calibration of the parameters is a prerequisite. In most cases, volumes, travel times and queues are...

Micro simulation programs are often used to assess the quality of traffic conditions. They are especially suited to evaluate possible control scenarios in advance, so that the scenarios can be selected and optimized before implementation. Of course, the simulation programs should be valid for the traffic situation that has to be modeled with respect to the relevant traffic characteristics. Cali...

This paper presents findings from a comparative evaluation of car-following behaviour in a number of microscopic traffic simulators. The paper describes the results of the calibration and validation of the car following model implemented in the ARTEMiS simulator developed by the author. The calibration and validation are based on a ‘standard’ car-following experiment (called the Boschtest) whic...

Kemajuan transportasi saat ini berkembang dengan sangat pesat, sehingga dapat menyebabkan terjadinya kemacetan, khususnya pada simpang. Salah satu penyebab lainnya yaitu penggunaan siklus dan urutan fase sistem Alat Pengatur Isyarat Lampu Lalulintas (APILL) masih menggunakan searah jarum jam atau sebaliknya yang mengakibatkan pengendara harus menunggu lama hingga lampu kembali hijau sedangkan a...

A unified platoon-based mathematical formulation called PAMSCOD is presented to perform arterial (network) traffic signal control while considering multiple travel modes in a vehicle-to-infrastructure communications environment. First, a headway-based platoon recognition algorithm is developed to identify pseudo-platoons given probe vehicles’ online information. It is assumed that passenger veh...

With the development of urbanization construction, urban travel has become a quite thorny and imminent problem. Some previous researches on the large urban traffic systems easily change into NPC problems. We purpose a multi-agent inductive control model based on the distributed approach. To describe the real traffic scene, this model designs four different types of intelligent agents, i.e. we r...

In this paper, we propose a consensus algorithm with input constraints for traffic light signals in transit signal priority (TSP). TSP ensures control strategy of traffic light signals can be adjusted and applied according to the real-time traffic status, and provides priority for buses. We give the convergence conditions of the consensus algorithms with and without input constraints in TSP res...

Vehicular Ad-hoc Networks (VANETS) have recently received great attention as a tool to disseminate information among vehicles with the dual purpose of increasing road safety and comfort in driving. Most of the messages that vehicles exchange are characterized by a finite lifetime period, after which, their level of usefulness is greatly reduced. Thus, an important problem in VANETS is to find e...

Emergency Vehicle is one of the rescue resources in a city. It is important to ensure safe and rapid emergency operations in case of emergency calls. This paper presents a signal priority control strategy for emergency vehicle operations in urban roads. The preset plans are discussed first to provide an optimal route considering the one-way coordinated signal setting, which focuses on the green...
