Modelling trip generation for road freight transportation in Kryvyi Rih

Abstract

The paper proposes a method for modelling demand generation (number of trips) in road freight transport within a four-stage demand model. This methodology is structured as follows: 1) urban freight transport is categorized into three distinct systems: light trucks (2.0 to 2.6 m in length, with two or more axles and a maximum carrying capacity of 2 t), medium three-axle trucks (over 2.6 m in length, with a carrying capacity ranging from 2 to 8 t), and three-axle dump trucks (with a carrying capacity exceeding 8 t). 2) In the procedures for trip generation and attraction, the number of jobs within transport districts is employed as a key structural indicator, which is then distributed according to the specific set of economic activities relevant to each freight transport system. To validate the proposed approach, a modelling of demand generation for freight transport in the transport model of Kryvyi Rih was conducted using the PTV Visum software. The results of the modeling demonstrated that the number of trips generated and attracted by different zones of the city matched, confirming the accuracy of the chosen method for calculating the trip generation for specific freight transport systems. It has been established that the production and attraction of trips by urban freight transport in Kryvyi Rih in the six zones where enterprises of the mining and metallurgical complex are situated is notably higher than in other zones within the model. These zones, referred to as mining areas in previous studies on urban mobility in Kryvyi Rih (specifically concerning passenger transport), exhibit distinct patterns in freight transport demand. Future research will focus on further procedures for calculating transport demand within the four-stage transport model.
