      <title>BUS DETECTION</title>
      <link>https://trid.trb.org/View/209250</link>
      <description><![CDATA[The structure of the bus detection system consisting of a detector's loop, amplifier and comparing unit is described. Details are given of the calculation of the detector's amplifier and comparing unit. The change in detector's loop inductivity is due to the passing of vehicles, the amplifier transforms it into an impulse and the comparing unit identifies the impulse given by a passing bus, transmitting to the signal equipment a request for a phase change when the red light is on. By giving priority to public transport vehicles it is possible to adhere to the timetable and to save fuel. For the covering abstract see IRRD 273856.]]></description>

      <title>IMPROVEMENT IN TRAFFIC CONTROL THROUGH THE USE OF STRATEGICALLY PLACED DETECTORS</title>
      <link>https://trid.trb.org/View/209251</link>
      <description><![CDATA[Strategically placed detectors can be directly connected to the microprocessor master controller. They are installed at strategic points in the area where the coordinated control of traffic signals is provided and they supply data on traffic intensity. The collected data are processed and used for the vehicle actuated primary and secondary time plan selection. For the covering abstract of the conference see IRRD 273856.]]></description>

      <title>POSSIBILITY OF USING SHUTTLE SERVICES AND CARPOOLING IN YUGOSLAVIA</title>
      <link>https://trid.trb.org/View/209253</link>
      <description><![CDATA[Within the transport system consisting of a network, vehicles and an organisation, changes in the organisation can be made easily and at a low cost. Between high-capacity vehicles for public transport, private cars and taxis, there is room for operation of small vehicles collectively organized. Possibilities of introducing new organized forms of transport by shuttle services and car pooling are discussed. These modes are already developed in many countries and partly in Yugoslavia. A wider use of these modes of transport would save transport costs considerably compared to private cars and taxis, and it would also provide better transport facilities without significant investment in these systems. The possibilities and effects of introducing new systems are observed with the aim of promoting these forms of transport.

      <title>MEASURES FOR THE IMPROVEMENT OF TRAMWAY CAPACITY, SPEED AND REGULARITY, AND LIGHT RAIL TRANSIT IN CITIES</title>
      <link>https://trid.trb.org/View/209254</link>
      <description><![CDATA[This paper presents a survey on the role and significance of public transport in cities and the potential performance of rail sub-systems, tramway and light rail transit. With the aim of achieving better transport, and of improving travel speed and regularity of vehicle's movements to increase the attractiveness of the services, a number of measures are proposed. They are grouped according to the areas they affect: terminals, intersections, stopping places, operation management, design of vehicles, tracks, etc. The proposed measures are described together with their possible application and expected effects. It is concluded that the present difficulties in financing the development of public transport and related infrastructure facilities should by no means slow down the planning, research and design processes. Conversly, necessary conditions must be provided and solutions prepared for immediate enforcement of the proposals.

      <title>RADIO SYSTEM FOR CONTROLLING THE REGULARITY OF DEPARTURES FOR PUBLIC TRANSPORT BUSES IN NOVI SAD</title>
      <link>https://trid.trb.org/View/209255</link>
      <description><![CDATA[Radio was introduced in the city transport system in 1965. The system was extended and modernized in 1972. The range of the radio station is about 50 kms and in good weather conditions even greater. The radio system comprises the main radio station, bus mobile radio station, repetitor and walkie-talkie radio station.  The main advantages of the radio system are: possibility of rapid intervention in case of bus damage, breakdown, repair and change of buses, intervention in special occasions on the lines according to road conditions etc. In the near future the existing system will be improved and enlarged on all the buses in the city.

      <title>NEW ROLE OF PUBLIC PASSENGER TRANSPORT IN CITIES</title>
      <link>https://trid.trb.org/View/203678</link>
      <description><![CDATA[The role of public transport in cities has been continually changing from the beginning of the 19th century to the present day. Its significance particularly increased in the second half of 19th century with the introduction of electric trams. Public transport has eliminated constraints in urban development planning and introduced a new dimension - time - in town planning. In Europe, during the first half of the 20th century, the role of public transport was further reinforced until the rapid growth in private car ownership brought about radical changes in transportation structures and caused a decline in the importance of passenger transport. As oil will continue to be expensive necessitating the rapid development of unconventional energy sources with sufficient supplies of electric energy, the forecast is that public transport will be the only mode fully capable of operating electrically-powered vehicles.

      <title>PROSPECT FOR THE USE OF MOTOR VEHICLES</title>
      <link>https://trid.trb.org/View/203909</link>
      <description><![CDATA[The energy crisis and current economic recession had unavoidable repercussions on the use of motor vehicles, making their future uncertain. In this paper, an attempt is made to consider the role of cars in the future, as well as the most important changes in the ways of using cars in Yugoslavia. The author expects that the annual mobility will remain at the level of 7-7500 km per car and the increase in the number of passenger cars will be reduced annually by 2 to 3% by the end of the decade, with the possibility of a recovery in the 1990s. The introduction of more economic cars, despite an absolute increase in the consumption of liquid fuel, which remains an irreplaceable kind of energy as far as motor vehicles are concerned, is discussed.

      <title>CORRIDOR TRAFFIC CONTROL - THE NEED FOR CONTINUOUS ACTION</title>
      <link>https://trid.trb.org/View/203911</link>
      <description><![CDATA[Conditions for optimum corridor traffic control are discussed. Traffic signal control is widely used as the main control strategy along corridors in Yugoslav cities, with adaptation to and modifications for real traffic situations. Unfortunately, in practice, the signal plans are not changed for years after their introduction, which can cause many problems. In order to solve those problems it is necessary to introduce a continuous process of traffic control and to develop new adaptive systems.  (TRRL)]]></description>
