Urban Wasteful Transport and Its Estimation Methods

Abstract

The paper studies urban road traffic problems from the perspective of resource science. The resource composition of urban road traffic system is analysed, and the road network is proved as a scarce resource in the system resource combination. According to the role of scarce resources, the decisive role of road capacity in urban traffic is inferred. Then the new academic viewpoint of “wasteful transport” was proposed. Through in-depth research, the paper defines the definition of wasteful transport and expounds its connotation. Through the flow-density relationship analysis of urban road traffic survey data, it is found that there is a clear boundary between normal and wasteful transport in urban traffic flow. On the basis of constructing the flow-density relationship model of road traffic, combined with investigation and analysis, the quantitative estimation method of wasteful transport is established. An empirical study on the traffic conditions of the Guoding section of Shanghai shows that there is wasteful transport and confirms the correctness of the wasteful transport theory and method. The research of urban wasteful transport also reveals that: (1) urban road traffic is not always effective; (2) traffic flow exceeding road capacity is wasteful transport, and traffic demand beyond the capacity of road capacity is an unreasonable demand for customers; (3) the explanation that the traffic congestion should apply the comprehensive theory of traffic engineering and resource economics; and (4) the wasteful transport theory and method may be one of the methods that can be applied to alleviate traffic congestion.

Collection of Waste from Passenger Ships and Its Impact on the Functioning of Tourist Port City Świnoujście

“…It is not a flexible resource, because their expansion is very costly and time-consuming, and sometimes even impossible due to the specificity of a given city. Properly organized waste disposal carried out in the city should take into account these resources, so as not to impede the fulfillment of other transport needs, although obviously waste transport will always be an additional burden on the city's transport system [15]. The road system of cities does not always enable the optimization of waste transport routes, thus requiring the introduction of other organizational solutions [24].…”

“…After collection, the waste is exported from ports to the places of their storage, use, or processing, often located in port cities or their surroundings. Means of transport cause additional traffic flow, which occupies the cities' traffic resources and causes normal traffic quantities of road sections or road networks to drop or congest [15,16]. They also burden the transport systems of cities, which are struggling with the growing problems of organization distribution of goods and services in urban areas [17].…”

The Methodological Standard to the Assessment of the Traffic Simulation in Real Time

“…Another important information is whether it is a special transport unit and whether special measures or training are needed to transport it (e.g., transport of dangerous substances-transport of ADR in road transport), etc. transport units to quantify the real costs of transporting a transport unit from point A to point B [18,19].…”
