Network management systems (German: Netzbeeinflussungsanlagen - NBA) are one possibility to manage traffic in the road network optimally in accordance with the existing traffic loads and travel times, especially in the event of disturbances in the traffic flow. The methods currently used for impact assessment of NBA based on the guideline “Hinweise...

The aim of the project was to evaluate a technical diversion method for vehicles at control points within the scope of stationary controls of the Federal Office for Goods Transport (BAG) in order to replace manual rejection by control personnel in the future. The technology, consisting of an operating station, camera technology and a control unit,...

Automatisierter und vernetzter Straßenverkehr kann erheblichen Einfluss auf die Leistungsfähigkeit zukünftiger städtischer Straßennetze haben. Um den Möglichkeitsraum etwas einzugrenzen und realistische Entwicklungen darzulegen, wurden in der Studie „Leistungssteigerung städtischer Straßennetze“ simulationsbasierte Untersuchungen durchgeführt. Di...

For haul truck drivers it is becoming increasingly difficult to find appropriate parking at the end of a shift. Proper, legal, and safe overnight parking spots are crucial for truck drivers in order for them to be able to comply with Hours of Service regulation, reduce fatigue, and improve road safety. The lack of parking spaces affects the backbon...

The ongoing increase of bicycle traffic in urban areas forces transport authorities to reconsider the space allocation for different transport modes. Transport policies favor the introduction of high-quality bicycle infrastructure along urban corridors to improve the traffic quality and safety for bicyclists but more importantly to increase the att...

Urban environments are more or less characterized by active travel modes, including the bicycle usage. Present transport infrastructure for bicyclists can often not serve the high traffic volumes, especially in rush hours. Therefore, introducing novel and specific traffic control strategies for bicyclists might serve as supportive element for impro...

Daily mobility has manifold appearances, especially in urban environments. Numerous modes of transport, different types of traffic participants and differing travel demands and supplies occur within often restricted urban infrastructures. One key for understanding these complex phenomena is the representation of not only space and time, but also of...

The bicycle traffic research group at the Chair of Traffic Engineering and Control at the Technical University of Munich use a physical bike simulator for various applications in different projects. Based on the connection of a steering and speed sensor, we can transfer movements of test subjects into different VR environments for evaluating variou...

Sitraffic SiBike is a mobile phone application developed by Siemens that prioritizes bicyclists at signalised intersections. Sitraffic SiBike has the potential to increase traffic efficiency and traffic safety for bicyclists. The prioritization reduces the number of stops of equipped bicyclists at signalised intersections. Additionally, travel spee...

This paper describes a systematic calibration process of a motorway network in Vissim, based on travel time measurements that were derived from limited number of Bluetooth detectors. The case study that is developed, establishes an example for practitioners that are interested in designing motorway networks with microscopic simulation tools. The th...

This paper analyzes the use of Bluetooth-based travel times, for Automatic Incident Detection (AID) purposes. Automatic incident messages were derived for both actual and simulated data through the use of an AID algorithm. This algorithm was developed by Technical University of Munich (TUM) and takes into account the travel times between two detect...

This article analyzes the use of Bluetooth-based travel times, for Automatic Incident Detection (AID) purposes. Automatic incident messages were derived for simulated data through the use of an AID algorithm, which was developed by Technical University of Munich (TUM). A Vissim model of a 15 kilometre section of A9 motorway in Germany was set up, w...

This paper describes a systematic calibration process of a Vissim model, based on data derived from BT detectors. It also provides instructions how to calibrate and validate a highway network model based upon a case study and establishes an example for practitioners that are interested in designing highway networks with micro simulation tools. With...

This article describes an approach to use travel times derived from Bluetooth detector data for dynamic net control in a freeway system for dynamic re-routing. The developed algorithms detect speed drops among sequenced vehicles and were implemented and tested in Northern Bavaria (Germany). Ongoing research aims at developing a fast, reliable and c...

The paper covers results of a test of deriving travel times from Bluetooth devices carried in vehicles at a motorway in Northern Bavaria. The test should clarify, if Bluetooth detection is capable of measuring vehicle travel times under motorway conditions and give insight to the characteristics of the data. Several practical prob-lems and solution...

Understanding the benefit of ramp metering facilities before they are built is an important task in the planning process. Hence, we propose a simple ex-ante evaluation that requires only a limited amount of data. Designed to be used by road authorities to check and justify the necessity of new ramp metering facilities, the proposed ex-ante (lat. fo...

Es wird ein System zur Qualitätssicherung streckenbezogener Verkehrsdaten vorgestellt. Aufbau und Funktionalität des Monitoringsystems orientieren sich an einem für Verkehrsdatenerfassungs- und Verkehrssteuerungssysteme entwickelten Benchmarkingsystem. Der vorliegende Artikel behandelt ausschließlich Lösungsansätze zur Überprüfung der Gerätetechnik...

Knowledge of accurate travel times between various origins and destinations is a valuable information for daily commuters as well as for security related organizations (BOS) during emergencies, disasters, or big events. In this paper, we present a method for automatic estimation of travel times based on image series acquired from the recently devel...
