      <title>Commuter exposure to black carbon, carbon monoxide, and noise in the mass transport khlong boats of Bangkok, Thailand</title>
      <link>https://trid.trb.org/View/1250913</link>
      <description><![CDATA[This work quantifies commuter exposure to black carbon, CO and noise when waiting for and travelling in the mass transport khlong (canal) boats in Bangkok, Thailand. Exposure to toxic pollutants and acute noise is similar or worse than for other transportation modes. Mean black carbon concentrations observed at one busy pier and along the main canal were much higher than ambient concentrations at sites impacted by vehicular traffic. Concentrations of CO were similar to those reported for roadside areas of Bangkok. The equivalent continuous sound levels registered at the landing pier were similar to those reported for roadsides, but values recorded inside the boats were significantly higher.]]></description>

      <title>Determining optimal transit charges: the Kiel Canal in Germany</title>
      <link>https://trid.trb.org/View/1245851</link>
      <description><![CDATA[The Kiel Canal in Germany connects ports on the Baltic Sea with the rest of the world and is the most-used artificial waterway in the world. Despite this fact, it generates a balance sheet loss. Revenues, which are mainly generated by the transit charge, do not cover its operating expenses. This situation raises the question how the current charging system could be redesigned to make the canal generate a balance sheet profit.  In this paper, the authors focus solely on the canal’s revenue. Because the canal is a monopoly that allows, in principle, for perfect price discrimination, they contrast the current charging system with an optimal charging system based on the willingness-to-pay (WTP) approach. The authors devise a general approach to calculate optimal transit charges and apply it in a case study that includes four ship types on three routes. The findings of the case study indicate that, in principle, much higher revenues could be generated if the transit charges were based not only on ship size but also on fuel prices and a ship’s departure and destination ports, as these affect a ship’s costs in terms of fuel costs and required sailing time.]]></description>

      <title>Climbing the Mountain: The Allegheny Portage Railroad</title>
      <link>https://trid.trb.org/View/849286</link>
      <description><![CDATA[In this article the author describes the historical Allegheny Portage Railroad, built in Pennsylvania between Philadelphia and Pittsburgh in the earlier 19th century as an economic competitor for the Erie Canal trade route. Despite many technical complications with building a canal over the Allegheny mountains, the state of Pennsylvania proceeded by connecting two stretches of canal on the east and west with a railway through the mountainous regions where a canal would not be feasible. Also required of the line was the first railway tunnel constructed in the U.S.  The railway was divided into two sections: levels and planes. The former of these were flat regions in the mountains where the railcars could be pulled along by horses and locomotives. Much of these loads were intermodal carriages designed to carry cargo by boat along the canal as well as on the rail. Plane regions were slopes where railcars were hauled using stationary steam engines and ropes. While the system was never a success economically for the state, the inventiveness and originality of the design are noted as an important landmark in the history of transportation in the U.S.]]></description>

      <title>Snakes and Ladders: Navigable Waterways as Invasion Corridors</title>
      <link>https://trid.trb.org/View/796157</link>
      <description><![CDATA[This chapter describes how the economic arguments in favor of the development of inland waterway infrastructure should not obscure their significant long-term cost to the environment.  Most inland waterways are no longer pristine:  watershed engineering, discharge of agricultural, industrial and domestic wastes, and power plant cooling water have contributed to varying impairments of the environment and harmed the native biota, which leaves it vulnerable to invasion or degradation.  Reconstruction of existing navigable waterways and constructions of new canal systems expedite the range expansion of taxa within the interconnected watersheds, which promotes both homogenization of faunas and secondary and tertiary invasions.  The rise in sea-river transport in the inland waterways transport market will enhance the spread of alien taxa that comes with transoceanic shipping.  With ample evidence that inland waterways serve as major invasion corridors, environmentally-considerate waterway engineering should include barriers that might preclude future invasions.]]></description>

      <title>Ohio on the Move - Transportation in the Buckeye State</title>
      <link>https://trid.trb.org/View/756209</link>
      <description><![CDATA[This book describes how few American states can match the rich and diverse transportation heritage of Ohio.  It discusses how every major form of public conveyance eventually has served the Buckeye state.  From the “Canal Age” to the “Interurban Era,” Ohio has emerged as a national leader.  The state’s central location, abundant natural resources, impressive wealth, shrewd business leadership, and episodes of good fortune explain the dynamic nature of the state’s transport past.  The book is the first systematic and scholarly account of the transportation history of Ohio.  To date, little has appeared on several of the subjects discussed in the book, including intercity bus and truck operations and commercial aviation.  The more familiar topics of river and lake transport, canals, steam railroads, electric interurbans, and mass transit are extensively explored in the Ohio context.]]></description>

      <title>WIDE LOAD: A NEW AQUEDUCT IN BELGIUM</title>
      <link>https://trid.trb.org/View/716038</link>
      <description><![CDATA[A new aqueduct is being built in Belgiun as part of a project to upgrade the country's Canal du Centre.  The construction of the Sart Canal Bridge is necessary for modernization of the canal. The aqueduct forms part of a new section of canal which will be capable of carrying the larger barges; it is designed to carry some 80,000 tons of water, eight times more than the live load of a road bridge.  Pedestrians will also be able to use the structure, walking along the 6 m wide service road on each side of the canal.]]></description>

      <title>THE LIUTO: A MODERN, LOW WAVE GENERATING, PASSENGER MB FOR WATER CITIES</title>
      <link>https://trid.trb.org/View/692969</link>
      <description><![CDATA[The only means of transport in Venice is constituted by waterways, which must be able to sustain the weight of both commercial and passenger traffic.  Passenger traffic overtakes during the high point of tourist season, which seems to be acceptable to preserve the historical buildings along the canal banks.  For the reason some limits to the wave generation in lagoon navigation have been imposed.  This paper presents an argument for the design of LIUTO, a modern vessel generating low wave and velocity fields, and in particular the results of the last study carried out in Venice in March 2000 which compared the wave and velocity field generated by the existing vessels and the one generated by the LUITO.  The diagrams shown demonstrate that the LIUTO generates a smaller velocity field wave with smaller total energy than the existing vessels.]]></description>

      <title>A SYSTEM FOR VESSEL TRAFFIC CONTROL IN CANALS AND STRAITS</title>
      <link>https://trid.trb.org/View/479729</link>
      <description><![CDATA[The purpose of modern sea and river navigation is to ensure ships safe passage and better vessel manoeuvring and guidance at sea and in rivers, taking into account the specific weather conditions and peculiarities of the region.  Target detection and tracking together with the capability to record current maritime events and recall them for subsequent use or multiple replay are among the features characteristics of a new, high-tech product generation.  The authors discuss their experience in designing a system of a similar class which helps solve the problem of vessel traffic control in straits and canals.  Experiments were carried out in the Gabchikovo river canal in the Republic of Slovakia.]]></description>

      <title>TRAFFIC GROWTH CONTAINS THE SEEDS OF FUTURE CHALLENGE</title>
      <link>https://trid.trb.org/View/456464</link>
      <description><![CDATA[The strong upturn in Panama Canal traffic levels continues, the 1994 figures were the highest since 1982 and it is expected that 1995 will surpass that record.  However, although new technology has changed the functioning structure of the canal, the waterway was not built to operate round-the-clock every day of the year and regular maintenance and repair works on ageing structures are increasingly straining transit expectations.  US jurisdiction will end within five years and the article discusses future investment requirements.]]></description>

      <title>A SYSTEM ANALYSIS FOR OPTIMAL MANAGEMENT OF CANAL SHIP TRAFFIC</title>
      <link>https://trid.trb.org/View/440851</link>
      <description><![CDATA[The article deals with technical problems associated with the management of ship traffic passing through a canal.  It examines the factors which are essential for the easy and safe passage of ships, calculates the passage times for various operational conditions and determines the throughput for different ship speeds and cycle times of canal operation.  The purpose of the article is to provide the appropriate authority with a tool to determine the optimal ship and canal operation.  Emphasis has been laid on the determination of the transit speed and the waiting time before entering the canal.  Ship speed is determined with due consideration of the installed engine power, the possibility of grounding, the likelihood of propeller cavitation and the possibility of damage to the waterway caused by the energy emanating from the ship.  The waiting time and the number of ships waiting at the canal entrance are calculated using methods of operations research.]]></description>

      <title>WHY EGYPT'S ECONOMY NEEDS THE SUEZ CANAL</title>
      <link>https://trid.trb.org/View/399802</link>
      <description><![CDATA[Some particulars are given from the figures released by the Suez Canal Authority covering Canal traffic for the first nine months of 1988.  Tonnage shifted significantly, with a fall in northbound volume about equaling a rise in southbound volume. About 50 ships a day transit the Canal, which is actually capable of handling twice that number. When the first phase of a program to widen and deepen the Canal is completed--which should be in 1990--the waterway will be accessible for 100 additional tankers of up to 200,000 dwt. The second phase, if plans are developed, will make it accessible to a further 305 tankers of up to 260,000 dwt. Toll discounts and the convoy system used for Canal transits are also discussed. The importance of Canal revenues to Egypt's economy is made clear.]]></description>

      <title>A STUDY OF THE PERFORMANCE OF LARGE BULK CARGO SHIPS IN A PROPOSED INTEROCEANIC CANAL</title>
      <link>https://trid.trb.org/View/159186</link>
      <description><![CDATA[The results of an experimental investigation of the performance of large bulk-cargo ships in a proposed interoceanic sea-level canal are presented.  Some significant characteristics of the performance of ships in confined water are brought out.  It is shown that a sea-level canal is feasible provided the canal is of adequate cross-section.  However, a very shallow canal or one with a very small cross-section area will severely limit the speed at which ships can transit the canal.]]></description>

      <title>PANAMA CANAL. ALASKAN OIL/PACIFIC BOOM BRINGS TRADE SURGE</title>
      <link>https://trid.trb.org/View/154353</link>
      <description><![CDATA[The boom in Pacific Basin trade--coupled with surging demand for Alaskan Oil--meant that last year Panama Canal tolls and tonnage hit record levels.  The figures available for transits so far this year are also encouraging, and they show that Altantic/Pacific and Pacific/Atlantic trade is still buoyant and has not yet been affected by the downturn in world industrial activity.  Oil,  which is dealt with in detail, now accounts for 40% of canal business.  But undoubtedly one of the most interesting aspects of canal development lies with dry bulk.  An investigation of shipping movements, for example, shows that a huge amount of tonnage ballasted through the waterway last year seeking business in the Pacific.  Equally fascinating are the large number of owners who found it more economic to transit the canal with full cargoes but low bunkers; they topped up with fuel on the US West Coast for their voyages across to Japan. In addition to discussing dry bulk carrier and tanker traffic through the Canal in 1979, the article examines the strategic importance of the Canal as an international waterway.  It further examines the economic importance of the Canal to Panama; that country's economic recovery since 1977 is due to the Canal Treaties with the U.S.  The article concludes with a discussion of Panama's future plans for the Canal and the possibility of a second canal.]]></description>
