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.
