Implementation of an Energy Model and a Charging Infrastructure in SUMO

Future traffic that will be accompanied by higher alternative drive concepts will pose as a challenge when it comes to corresponding energy systems, coordination of operations, and communication interfaces, such as needed for data acquisition and billing. On one hand, the increasing attractiveness of electric vehicles will inevitably lead to the development and testing of compatible technologies; on the other, these will need to be conformed to existing systems, when integrating them into the prevailing infrastructure and traffic. Funded by the German Federal Ministry of Transport, Building and Urban Development, an inductive vehicle charging system and a compatible prototype bus fleet shall be integrated into Braunschweig’s traffic infrastructure in the scope of the project emil (Elektromobilitat mittels induktiver Ladung – electric mobility via inductive charging). This paper describes the functional implementations in SUMO that are required by the methodic approach for the evaluation of novel charging infrastructures by means of traffic simulation.

Simulation Based Studies on the Integration of Battery-Electric Vehicles in Regional Bus Services

Around the world, more and more cities already have introduced electric-powered bus fleets or are planning to do so in the near future. Thus far, electrical-powered bus fleets have not yet been applied to regional bus services. This paper analyzes the boundary conditions of the operational integration of electrically powered bus fleets in regional bus services. The paper introduces a methodical approach which can be used to identify the optimum deployment strategy for electrical-powered buses which is a combination of technological factors (e.g. dimensions of energy storage and charging technology) the operational regime to be applied (e.g. routing and scheduling). The methodical approach is exemplarily instantiated with the analysis of sample data of a bus line in a topographically challenging region. The model-driven prognosis of the vehicles state of charge is the basis for the definition of an optimum deployment strategy for electrical-powered buses on that line.

Extending a traffic simulation tool for the evaluation of novel charging infrastructures

The limited amount of fossil energy sources will inevitably require the development of alternative energy supply systems to satisfy our persisting demand for mobility. Future traffic will therefore pose a challenge when it comes to the corresponding technologies, coordination of operations, and communication interfaces, such as needed for data acquisition and extra-vehicular communication. The increasing attractiveness of alternative drive and energy supply concepts will on one hand allow for new possibilities in testing new technologies; on the other, the new developments will need to be conformed to existing systems and technologies. Funded by the German Federal Ministry of Transport, Building and Urban Development, the aim of project emil (Elektromobilität mittels induktiver Ladung - electric mobility via inductive charging) is to integrate an inductive vehicle charging system and a compatible prototype bus fleet into Braunschweigs traffic and infrastructure. This paper shall describe the required functionalities and methodic approach for the evaluation of the new infrastructure by means of traffic simulation and outline the possible optimization potentials it offers.

Energy transfer for electric traffic

This contribution deals with the aspects of integrating new charging infrastructure into traffic. Due to the ease of its handling, the inductive energy transfer offers promising solutions for charging vehicles during their operation without additional halts as they are currently required at gas stations. The requirements for these future charging systems and their integration into traffic systems shall be outlined in regard of number of required infrastructure elements, charging power, and their optimal placement in the road network. The methodology uses microscopic traffic simulations for the analysis of road traffic and its participants.

eNetEditor: A Platform-Independent Tool for Rapid Creation of Urban Traffic Scenarios and for the Optimization of Their Energy Supply Infrastructure

The increasing mobility and transport demand and the sinking global supply of fossil energy carriers will eventually cause a growing trend toward alternative drive concepts and the development of corresponding energy supply infrastructures. These emerging solutions and their interaction with the prevailing traffic will need to be evaluated for their optimal integration. SUMO is a preferred tool when it comes to evaluating measures in urban traffic behavior. When using SUMO, however, the creation of corresponding scenarios is accompanied by challenges in network creation and corrections, traffic demand generation and calibration. This paper presents the newly developed tool eNetEditor, which allows users the rapid prototyping of custom and calibrated traffic scenarios and their evaluation in regard to energy consumption.
