Summary - Lecture 3: Urban Transportation Systems “The Limit to Urban Growth in Transport - from Congestion, Low Carbon to SDGs”

  1. 1. 1 2018 ProSPER.Net Young Researchers’ School ‘Sustainable Urban Development for the World’s Megacities’ Urban Transportation Systems “The Limit to Urban Growth in Transport - from Congestion, Low Carbon to SDGs” Presented by Prof. Yoshitsugu Hayashi (Chubu University) Summarized by Nowar Raad Abdalmajeed & Sameera Darshana Jayasooriya Edirisinghe Mudiyanselage New report to the club of room: come on, Prof. Hayashi “what he recommended to read” Summary In the first part of presentation content, Prof. Hayashi have focused on issue of limit to growth in resources. He explained that both the Gross domestic product (GDP) play a main role in efficiency of resources, while the Quality of life (QOL) affects the sufficiency of resources. He also compared between developing and developed countries with regards to increasing in population. The decreasing in natural resources and food against the increasing in growth population were also explained in detailed chart prepared using system dynamics simulation for period from 1900 to 2100. The current important issues regarding limit to growth were identified by Prof. Hayashi in two points. The first one was the necessary of transformation from one-way economy to circular economy and the second point was long term or holistic thinking or critical thinking with regard to addressing the issues of limit to growth. Then, the seeking for low carbon transport was discussed by Prof. Hayashi. He detailed the effects of integrated transport system on traffic congestion and CO2 mitigation. He referred to the importance of moving toward used more sustainable mobility and he explained the negative impacts of CO2 emission on environment and society. In one diagram, he compared different types of transports such as car, truck, rail and bus against different functions of land use in terms of CO2 emission and motorize speed. A main framework for strategic actions called CUTE policy/technology matrix or Avoid-Shift-Improve approach was also discussed in the same context. According to this approach, infrastructure is clearly provided in such a way that: i) future travel domain is reduced or avoided; ii) travel is shifted to more friendly environment and economic models; iii) technological measures improve the vehicle fleet and fuel. The last thing presented in this part was the comparison between road and rail in terms of any type of these transport systems is more effective for calming traffic congestion. In the final part, how to measure the personal quality of life (QOL) for evaluating the inclusiveness in SDGs was discussed. The theory of QOL that have been presented in this context was the sharing values by better accessibility. These values was divided into existing values, accessible values and perceived values and each type of these values is calculated by a specific equation. On the other hand, weighting the factors affecting QOL in Singapore between young, middle-age and aged for both female and male were presented as an example. Finally, Prof. Hayashi have completed his presentation with important issue regarding the city of SDGs. He concluded that there are three issues should be achieved for contribution in creating the city of SDGs. The first issue is achieving sustainability by: i) low
  2. 2. 2 resource consumption; ii) low pollution & low carbon; and iii) less damage on the earth. The second issue is the higher quality of life by higher GDP and well-being for people in an aging/aged society (from efficiency to sufficiency). The final issue is circular and green economy system. One of the important point highlighted by audience and totally agreed by Prof. Hayashi was the role of accessible and affordable public transport service and safe infrastructure for non-motorized transport such as cycling and walking in contribution for more sustainable environment and mitigation of congestion problem. Finally, Prof. Hayashi have answered all audiences’ inquiries and gave his advices for students and shared the participants the dinner and then safely left meeting place.
