Efficient Methodology for Assessment of Targets and Policy Measures for Sustainable Mobility Systems

The development of transport policy measures to reduce negative environmental impacts and social costs is crucial for decision makers and traffic researchers seeking ways to decrease transport demand (mostly passenger car) and congestion levels. This paper proposes a methodology for testing optimal public transport (PT) to passenger car (PC) usage ratios in order to reduce negative environmental impacts and external costs as a part of social costs by implementing proposed transport policy measures. The effects of different city transport policies on the total transport demand of PC and PT during morning peak period in Novi Sad, Serbia, were tested through a traffic macroscopic simulation procedure. Traffic flow distribution outputs were used to estimate external costs and pollution emissions in proposed current situation scenarios. The results of this study enable the development of sustainable transport strategies through identification of different combinations of mobility management measures that would produce desired outcomes.

Target modal split model

Abstract The research presented in this paper is aimed at defining a model that enables the management of the relationship between private vehicles and public transport applying the available instruments of city transport policy such as parking policy and public transport policy measures. Statistical data used for modelling is sourced from the database in a wide range of EU cities. The target model was developed in the form of stepwise regression analysis. Very favourable statistical results were obtained, and the subsequent tests on the city of Novi Sad (250000 inhabitants) led to the conclusion that the obtained results were suitable for implementation in practice. The results of the implemented procedure are of great importance for the enhancement of the existing transport policies in cities, as they enable the development of strategies for finding combinations of instruments that would bring the transport system and urban environment into a desired-viable rather than consequential condition.

Model and software-based solution for implementing coordinated timed-transfer passenger transport system

For a number of users, transfers are an unavoidable aspect of travel, irrespective of the public transport network quality. Transfer time not only extend the journey time, but also affect service quality. That is especially expressed on low-frequency lines. Implementation of timed transfer system (TTS) on low-frequency lines reduces temporal losses to acceptable limits. Transport network type, transport hub location, uneven transport demand across routes, performance differentials among subsystems and variable vehicle capacities further hinder the already complex TTS design. This work presents the procedure and software for efficient alignment of static and dynamic elements of coordinated lines in the process of establishing a TTS for chosen public transport network lines.
