Summary of Presentation
This seminar will focus on a few components concerning the linkage, interrelationship, and the need to collaborate between land, road, rail, bus and ferry services. It will attempt to show how to deal with and to solve in a practical manner current operations-planning dilemmas and confusions follows Pablo Picasso, who said: "I do not seek, I find." This presentation will provide solution approaches, examples and offer ways to improve and optimize the Land-Road-Rail-Bus-Ferry system.
Following the introduction and background materials it will be shown how important are the land interchanges that are especially design for intermodal services. This is where the land, road, rail, bus, and ferry can meet for helping to transfer passengers and freight. It is well known that ideally people and freight desire to move door-to-door with a ‘seamless’ service. The complexity of the urban network enforces the use of transfers. However, it is in our hands to make these transfers almost ‘seamless’ with a better planning and design.
Improving the connectivity of the public-transport system is one of the most vital tasks in transportation operations planning. A poor connection can cause some passengers to stop using the transit service. Service-design criteria always contain postulates to improve routing and scheduling coordination (intra- and inter-agency transfer centers/points and synchronized/timed transfers). Ostensibly the lack of well-defined connectivity measures precludes the weighing and quantifying of the result of any coordination effort. The presentation will provide an initial methodological framework and concepts for (i) quantifying transit connectivity measures and (ii) directions and tools for detecting weak segments in inter-route and inter-modal chains (paths) for possible revisions/changes.
One possible definition of a prudent, well-connected transit path is this: An advanced, attractive transit system that operates reliably and relatively rapidly, with smooth (ease of) synchronized transfers, part of the door-to-door passenger chain. The presentation will show how to attain such well-connected paths with the use of interchanges/terminals/stations exhibiting land requirements and optimal tactics and strategies. Overall the presentation will attempt to answer the questions:
· How to measure the connectivity or coordination of public-transport system ?
· How to detect current or anticipated weaknesses and bottlenecks in inter-route and/or inter-modal chains/paths ?
Finally some remarks will be made in the presentation, using slides, about what can be done and how in order to shift a significant number of car users to transit in a sustainable manner. It is believed, including for public-transport systems in P. R. China, that the answer is in a more efficient transportation network using some new concepts, some of which to be relied on on-line information of both the passengers and vehicles.

Bio of Professor Avi Ceder
Avishai (Avi) Ceder received B.Sc. (1971) at the Technion, Faculty of Industrial and Management Engineering. M.Sc. (1972) and Ph.D. (1975) on the subject of Transportation with emphasis on Operations Research and Human Factors, at the University of California at Berkeley, USA. In 2007 he arrived to the University of Auckland to take the position of Professor - Chair in Transportation, within the Department of Civil and Environmental Engineering; he is the Founder and was the Director, until 2014, of the transportation research centre (TRC). Avi was Head of the Transportation Engineering and Geo-Information Department at the Technion, the Chief Scientist at the Israel Ministry of Transport from 1994 to 1997, and the Israel delegate to the Transport Program of the European Community. Avi was a visiting Professor twice at MIT, the University of California at Berkeley, and at Universities of Hong Kong and Tokyo, and he is a member of various international symposia and workshops (e.g., ISTTT, CASPT). In 2007 he released the book ‘Public Transit Planning and Operation: Theory, Modelling and Practice’, by Elsevier, UK, which was translated to Chinese by Tsinghua Press, Beijing, 2010; its 2nd edition to appear in 2014, by CRC Press, Taylor & Francis.
