The MUTCD is published by the Federal Highway Administration (FHWA) under 23 Code of Federal Regulations (CFR), Part 655, Subpart F. The MUTCD, which has been administered by the FHWA since 1971, is a compilation of national standards for all traffic control devices, including road markings, highway signs, and traffic signals. It is updated periodically to accommodate the nation's changing transportation needs and address new safety technologies, traffic control tools, and traffic management techniques.

Fahrradpiktogramme auf der Fahrbahn können genutzt werden, um Radfahrende in beengten Verhältnissen auf ihr Recht, auf der Fahrbahn zu fahren, aufmerksam zu machen. Gleichzeitig dienen sie als Hinweis für Kfz-Fahrende, auf Radfahrende auf der Fahrbahn vorbereitet zu sein und diesen rücksichtsvoll zu begegnen. International sind sicherheitsförderliche Effekte der Maßnahmen gut belegt, eine Untersuchung im deutschen Verkehrskontext stand bisher jedoch noch aus. Stefanie Ruf begleitet die Umsetzung von Piktogrammen in verschiedenen deutschen Kommunen mit Vorher-Nachher-Befragungen im Feld sowie mit einer ergänzenden kontrollierten Online-Befragung. Ihre Erkenntnisse zeigen, dass Fahrradpiktogramme auf der Fahrbahn auch in Deutschland einen Beitrag zu Flächengerechtigkeit und Verkehrssicherheit leisten können, gleichzeitig werden auch wichtige Einschränkungen diskutiert.

Most contemporary notions of the fairly recent concept ¿smart mobility¿ portray an imminent transition of similar socio-economic consequences as the shift from horses to automobiles did 100 years ago. Present book thus offers an in-depth look at the variables involved in the equation of smart mobility acceptance (1) and envisaged institutional change (2).Both views are embedded in the Multi-Level Perspective. Study 1 develops a structural equation model in SmartPLS. Use cases cover eBikes (N=537), mobility-as-a-service (N=531), and fully automated vehicles (N=558). Based on the results, acceptance relies on five factors: performance expectancy, facilitating conditions, social influence, habit, and hedonic motivation.Study 2 applies the Institutional Role Model (IRM) to better understand system dynamics. Thus, the smart mobility ecosystem is mapped in a structured manner. It identifies nine institutions, as well as four technical and four economic roles. Results of interviews with experts (N=8) support the IRM¿s significance as a vision provider for a new mobility regime.In the end, these two perspectives amalgamate. This opens a sophisticated space for public debate about the commencing transition to smart mobility.

This book supports companies in the transport sector, political decision-makers, transport engineers, planners and scientists doing fundamental research who are confronted by growing challenges in transport. These challenges arise from a number of powerful socio-technical trends, including: digitalisation, globalisation, urbanisation, and the requirements of individual users and the increased need to reduce environmental impact of transport. Providing the innovations required to cope with these challenges is not a simple matter.Towards Innovative Transport Systems structures and compiles theoretical foundations from evolutionary economics, the sociology of technology and innovation research in a way that provides a broad understanding of innovation processes without demanding prior knowledge. Using the Concept of Transport System Evolution (CTSE), it explains in depth the economics of innovation in the transport sector, thus contextualising processes, drivers and obstacles at work in current practice; among such processes are the changeover to electric mobility, the realization of autonomous cars, the revival of railway by innovations and dealing with disruptive innovations in transport. The CTSE is an approach to making concrete the multi-level perspective for the transport sector introduced by Frank Geels. On the basis of the CTSE, the author proposes principles for a novel innovation policy in transport that can serve the reader as a guide when making strategic decisions.
