Basic Requirements for Urban Cars

1978-02-01
780219
To find the minimum range, speed, and capacity required to meet most needs of urban drivers, origin-destination surveys from Los Angeles and Washington were processed to determine driving patterns for a typical day. ...The survey data indicates that ranges sufficient for 95% of driving days would be 75 km for secondary drivers, 150 km for only drivers, and 225 km for primary drivers at urban households. Similarly, speed adequate for freeway use is required to satisfy driver needs on 95% of driving days, with seating for at least two and generally three passengers in addition to the driver.

The Iconography of Urban Systems

1972-02-01
720652
Neither the architect, in his preoccupation with individual projects and mere pieces of cityscape, nor the engineer, in his willingness to slice into the living tissue of the city without understanding its socio-environmental pathology, is trained to cope with our problems of urban design. Yet is is the vast technical networks of movement that are the lifeblood of our cities, and have the most promise of providing an infrastructure capable of ordering growth and change in our cities. ...However, urban sociologists are preoccupied with problems of social diagnosis, architects reject technology as a conceptual skeleton for their esthetic games, and engineers seem unable to grasp the vast esthetic implications of transportation technology in the cityscape of tomorrow.

Gasoline Consumption in Urban Traffic

1976-02-01
760048
Fuel consumption and dynamical variable data have been collected as a car was driven normally with low speed urban traffic. It has been shown, using regression analysis, that the single traffic variable of the 16 studied that can best explain fuel consumption per unit distance is the average trip time per unit distance. ...An interpretation of this result is given in terms of engine-vehicle dynamics and the characteristics of urban traffic. The analysis of the data for each of four different drivers showed that the fuel consumed per unit distance was determined mainly by the average trip time per unit distance, essentially independent of the individual driver.

This paper describes techniques and other significant factors to satisfy good maintenance, consistent with the control and abatement of diesel exhaust emissions in urban transit operations. Major stress is placed on the use of instruments, not only for inspection, diagnosing, and correcting obvious faults which cause black and blue smoke, but also for monitoring engine deterioration and indicating when motor and torque oil should be changed.

Transportation Needs of Urban Systems

1972-02-01
720567
An attempt is made to show that a transportation system as such is too "open" for sound planning, and that the larger interaction system (including the users of transportation and their bases at home and work) must be considered. This requires a detailed understanding of micro-behavior, social goals, and public policy alternatives in a wide range of situations.

Over the last decades, a tremendous effort has been made by the European Commission to control the amount of pollution in urban areas by means of EC directives to limit emissions. Today one of the main problems in urban areas is the particulate matter, predominantly emitted by diesel engines. ...In this scenario, the research group of the University of Rome “Tor Vergata” has undertaken a research project with the aim of identifying the benefits of new drive system technologies for urban buses. In this work, the potential benefits of replacing Diesel engines with two different hybrid powertrains are shown. ...To obtain a projection of the beneficial effects of the hybridization on the urban area of Rome, numerical simulations have been carried out on some “real” driving cycles corresponding to real bus routes.
