Motorways participate insufficiently in solving of the traffic problems in the Croatian big cities, so that it is necessary to undertake measures which would revitalize motorways and enable their
integration into the traffic systems of the Croatian cities, with the use of the already tested world and  European  models.  The  problem  points  to  the  fact  that  Croatia  has  the  highest  number  of motorways  in  relation  to  $  billion  of  GDP,  that  there  is  the  lowest  number  of  junctions  at Croatian  motorways,  and  that  the  distance  between  them  is  the  longest.  The  traffic  load  on  the Croatian  motorways  expressed  in  the  number  of  vehicle-kilometres  per  motorway  kilometre  is amongst the lowest in the World, and there is the highest distance between Croatian motorways and the centres of the big cities they connect.

This paper explores the possible transportation and property value impacts of a new  congestion management policy called credit-based congestion pricing (CBCP). Integrated land usetransportation models provide short- and long-term estimates of travel demand, network operations, location choice, and land use patterns. Using destination, mode and departure time choice models sensitive to changes in travel times and costs, household travel demands were simulated in order to appreciate the transportation effects of a CBCP policy for Austin, Texas. Changes in land use, locational accessibility and property values as a result of CBCP also were simulated. The trip-based welfare impacts of such a policy were compared for three scenarios (full network pricing, major highway pricing only, and no pricing), in order to identify households and neighborhoods that will benefit most and least from such policies. The results corroborate prior results and hypotheses about the potential of a CBCP policy to alleviate congestion and generate benefits across the region income groups and traveler types.

Key words: Credit-based congestion pricing, travel demand modeling, welfare, property value
models, transportation policy

The New York City, New Jersey Metropolitan area transit, highway, bridge, and tunnel systems are the arteries that move the life blood in the region. 37 million people live within a 30 mile radius, and tens of millions of annual tourists and business travelers using this transportation network make a significant contribution to the regional economy. Linking the myriad of payments systems into one unified electronic system will improve services, reduce costs, and encourage great use of transit for this market.

This year we will be testing smart cards for New Jersey Transit rail customers traveling to Newark International Airport. These smart cards will be used to access the AirTrain fare gates at the new Northeast Corridor station. Smart cards will also be incorporated next year into the fare payments system for the new John F. Kennedy International Airport AirTrain. At the same time, we are exploring a new PATH fare collection system incorporating both MetroCard and smart card capability. And in time, smart cards will be issued for other New Jersey Transit and Metropolitan Transportation Authority bus and rail riders.

This article presents an express lane network concept called “High Occupancy
Vehicle-Credit” or HOT-C lanes that could be implemented in a short period of time.  A network of free-flowing express lanes would be created by re-striping freeways to convert the left general-purpose lane(s) into HOT-C lanes during rush hours and creating a dynamic shoulder lane on the right side to replace the converted left general-purpose lane.  To gain public acceptance, a limited quota of credits would be made available to all employees in the
metropolitan area for free use of the lanes during rush hours.

The GCM Gateway TIS is currently being developed as the central traveler information hub for the Gary-Chicago-Milwaukee Corridor and will be operational this fall to replace an existing legacy system. The Gateway TIS collects transportation related information from geographically widely distributed agencies of varied natures, validates and fuses the information collected, and disseminates it to interested public and private entities and the general public via internet and intranet. The Gateway handles a wide spectrum of data types, including traffic related incidents, roadwork and special events, vehicle detector data, DMS (Dynamic Variable Sign) and HAR (Highway Advisory Radio) messages, weather sensor data, traffic operational parameters derived from electronic toll collection system. Eventually, The Gateway will also provide real time video services.

This paper presents at a high level the CORBA based system architecture design of the Gateway system primarily from the perspective of ITS Center-to-Center interoperability. It also introduces the object oriented Gateway external data model that is specified in CORBA IDL (Interface Definition Language) and the Gateway Publisher/Subscriber based message oriented middleware for data collection and distribution. In addition, the Gateway’s decision on the selection of object oriented DBMS (Database Management System) versus relational DBMS is also discussed.
