    The potential in urban environments of innovative public transport systems based on automation is being investigated within the CityMobil project (2006-2011). The Rome demonstration is implementing a cybernetic transport system (CTS) to connect the new fair with the car park. For this, a demand study has been carried out with a view to assessing the attitudes of the users towards innovative and conventional systems. A stated preference survey has been designed based on two questionnaires: one for the choice between foot and CTS, one for the choice between foot and a minibus. The responses to the two questionnaires have been pooled and a logit model has been calibrated using the joint maximum likelihood. The results are indicative of the relative preference of the users for innovation, as the demand for CTS is higher than the demand for minibus, the scenario and level-of-service attributes being the same. The hypothesis of heterogeneity across individuals of the attitude towards innovation is tested using a mixed logit formulation. Finally, the variation of preferences with the characteristics of the users, including gender, age and education, is explored

    Master’s degree. University of KwaZulu-Natal, Durban.Rapid urbanisation in the last century resulted in a more urban population although some countries and continents still have higher rural population. It is estimated that by the year 2050 more than 75% of the world‟s population will be living in urban areas (WB, 2013; OECD, 2015). Most of this increase in global urbanisation is forecast to take place in the emerging, developing and less developed, or third world Africa, Asia and South America (Pojani & Stead, 2015). Transport plays a critically important role within urban areas in ensuring that urban dwellers gain access to resources and socioeconomic opportunities. The transport systems in most urbanized and urbanizing areas of developing nations are largely unsustainable and cause numerous problems that directly affect the quality of social, economic and environmental urban systems. With limited access to financial capital and strong institutional structures these nations struggle to develop their urban infrastructures to keep up with the increasing human populations and demands of safe, reliable and sustainable transportation services. The information and communications technology (ICT) sector has recorded unprecedented growth in Africa over the last decade. In Zimbabwe, for example, telecommunications technology, in the form of an electronic mobile payment system, has enabled the sustainable growth of the informal economy by creating a cashless society. The system has enabled the poorest of citizens access to financial and credit facilities and helped them start up and run profitable small businesses (www.econetwireless.com). It provided a sustainable solution for managing the financial crisis in the country. With more than 75% of the population now owning mobile telephones and wireless devices technologies like the payment systems can be used to improve other sectors of the economy currently under stress and strain. This research study intends to investigate the use of advanced transport systems and technologies in improving transport in the major urban centers of Zimbabwe. The study will investigate intelligent transport systems as tools of improving urban transport and how their operational and functional requirements can be used by design professional to create sustainable and meaningful urban built form

    Pre-design method for advanced public transport systems

    Thanks to vehicle automation, a new generation of urban transport systems that can supply car-like quality of service with Public Transport-like impacts was made possible. They are called Advanced Public Transport Systems and consist of small automated collective vehicles running on demand. A pre-design method for a first dimensioning of such systems was developed by simulating nearly 3?000 scenarios with Dial-A-Ride software and performing statistical regressions on the results. The method needs as input: network length, expected demand, vehicle top speed, maximum waiting time, and vehicle capacity. In six steps the method gives: number of vehicles, average waiting time, vehicle?kilometers, commercial speed, occupancy rate, and costs. The regressions are given for 20-place vehicles, 15 km/h top speed, and 1?000 s waiting time CTS. All the R 2 coefficients are higher than 0.75 and in most cases than 0.85. Empirical validations, made by comparing pre-design regressions with other system data, showed that the method gives accurate results
