While the trend towards the growth of megacities creates huge challenges, it also offers the opportunity for reshaping mobility patterns in cities, promoting energy efficiency and principles of low carbon development. In this volume, an overview is provided of solutions comprising concepts for sustainable transportation through intelligent management, innovative instruments for integrated transport planning, modelling systems, adaptation strategies in the transport sector and concepts for enhancing public transit. Developed for five cities of the programme by transdisciplinary and international research teams in close collaboration with local stakeholders, they are presented on the background of big challenges ranging from data collection issues, modelling and planning in a fast growing environment to resistance of citizens against big infrastructure projects.
In many countries, a focus on expanding road-based transportation has led to increased individual car traffic, resulting in higher road demand and negative external effects on urban living and working conditions. In the past decade, particularly in the MENA region, municipalities have sought to curb car traffic growth and promote environmentally-friendly mobility concepts. However, many of these initiatives, while ambitious and innovative, have often been implemented in a fragmented manner. Research conducted during the Young Cities project, part of the BMBF-funded Megacities program, examined the urban transport sector in the MENA region, with a specific focus on Iran. Findings indicated a lack of coordination between the Urban Transportation Masterplan and public transport operators in Iran. This publication analyzes the Local (Public) Transport Plan, a tool used globally to establish quality and service standards for urban public transport. It also explores the Iranian urban transport planning system and offers recommendations for adapting this tool to better suit Iranian conditions.
High energy consumption in the Tehran region leads to significant CO2 emissions, with residential and commercial buildings accounting for 41% and transportation for 25% as of 2008. This publication estimates the impact of various planning fields in New Town Hashtgerd and the Tehran-Karaj region on CO2 emissions, focusing on mixed-use buildings, office buildings, and transportation. It evaluates the potential CO2 reduction from implementing findings and recommendations from the Young Cities project. CO2 emissions are calculated based on energy consumption, energy simulations, and emission factors for different energy sources. Initial emissions are assessed for Hashtgerd New Town and then extrapolated for the entire former Tehran province, estimating per capita emissions for 2027 under two scenarios. The “business as usual 2027” scenario reflects current trends, while the “planning scenario 2027” assumes that 2% of new buildings follow Young Cities' recommendations and a new transportation system is adopted. The comparison highlights potential CO2 reductions achievable through these measures. The findings suggest significant emission savings compared to conventional approaches, although the results are based on simulation algorithms and assumptions. To achieve a comprehensive CO2 balance in Hashtgerd, other energy-intensive sectors like industry and agriculture must also be considered. Overall, the results emphasize the effectiv
Die Beherrschung logistischer Prozesse entwickelt sich zunehmend zum entscheidenden Wettbewerbsfaktor. Ausgehend von Methoden zur Analyse des Ist-Zustandes und zur Definition von Zielsystemen werden in diesem didaktisch gut konzipierten Lehrbuch alle wichtigen Konzepte des Logistikmanagements konkret, ausführlich und leicht verständlich erklärt. Zwei handlungsorientierte Planspiele sowie Kompakteinführungen in die Softwaretools ARIS und Powersim, die häufig zur Prozessoptimierung verwendet werden, zeigen beispielhafte Vorgehensweisen.
