In vielen Städten ist die Reduzierung des motorisierten Individualverkehrs (MIV) erklärtes Ziel der Verkehrspolitik. Als Erfolgsmaßstab dient häufig der Modal Split, in der Regel ausgedrückt als Anteile der Verkehrsmittel an den zurückgelegten Wegen (relativer Modal Split). Dabei wird oft vor allem die Entwicklung des MIV-Anteils betrachtet. In einigen deutschen Städten ist der MIV-Anteil in den letzten Jahrzehnten gesunken. Die hier präsentierten Daten aus Verkehrserhebungen in Großstädten (vertieft betrachtet Münster und Hannover) zeigen aber, dass der relative Modal Split des Bewohnerverkehrs zu deutlichen Fehleinschätzungen der tatsächlichen Verkehrsentwicklung verleiten kann.

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.

Ein möglicher Ansatzpunkt zur Reduzierung der Treibhausgasemissionen des Verkehrs besteht im Verbot bzw. Wegfall des Inlandsluftverkehrs in Deutschland. In diesem Papier wird der Einfluss einer solchen Maßnahme auf die Verkehrsleistung, den Modal Split und die Treibhausgasemissionen im innerdeutschen Personenfernverkehr untersucht. Dazu wird ein systemdynamisches Simulationsmodell verwendet, mit dem sich künftige Entwicklungen auf dem Personenfernverkehrsmarkt abschätzen lassen. Die Ergebnisse zeigen, dass ein Verbot von Inlandsflügen allein kontraproduktiv im Hinblick auf die verkehrs- und klimapolitischen Ziele wirkt.

The subject matter of this study pertains to the population of Aizawl city, Mizoram. The data is based on the usage of public or private transportation by individuals irrespective of their ownership of private vehicles. The sample includes respondents who are teachers,high-school and college teachers taken separately, of all age groups, different educational backgrounds, as also different income levels who are mobile, belonging to Aizawl city and around.The study examines only the demand side factors influencing travel decisions. The supply side aspects, relating to public transports are taken as given. A study of this kind is beneficial to many parties like the government in its policy implication and also to the private entities as it is directed towards reduced travel expense. Insight of the mechanisms of the travel decision process will benefit governments to formulate policies that better address consumers needs in transport. The study will also enable public transport managers to understand their consumers needs preference and psyche. Furthermore, since no study of this nature has been conducted for the city of Aizawl, the present study will contribute to the birth of a recorded empirical work. It will also lead to further, deeper, more significant research in the area.This study attempts to contribute to the understanding of how local public transport demand is affected by different factors. The focus of this study is to examine the cause of preference of public transportation over private or vice versa by passengers. Considering the increased use of public transportation by individuals and especially by those who also own private vehicles, it is important to understand what causes this preference of one means over the other and the personal benefits involved with it. Careful analysis also shows that the respondents prefer private transportation to public. The logit model shows that of the variables affecting transport mode choice by individual among high school teachers that is most significant is ...

Most scholars believe that the journey to work is vital in any aspect of land-use and transport planning. Transport remains a vital component of the urban economy that enables the populace to move freely between their homes and places of work. This study examines the factors that influence modes of travel used by the commuters in the suburb of Mabelreign as a first step towards isolating the causes of transport problems in Harare. This way the needs of different socioeconomic groups can be understood. An attempt is also made in this study to use simple travel models in determining modal split. These models are adapted in the context of the study area. Questionnaire surveys and interviews are also used in establishing the modes of travel used and factors influencing the modes of travel. The survey results showed that a large split of the travellers (64.2 per cent) use private transport (cars), 9.1 per cent use buses and 24.3 per cent use commuter omnibuses. Route with a shorter travel time tend to be favoured over routes with longer travel times. In Mabelreign, 60.1 per cent own cars as compared to 67.7 per cent who use cars to work – a phenomenon explained by the increased use of lift clubs in order to reduce costs. Inconvenience factors, both from the service and vehicle comfort viewpoints have greatly influenced the decline in public transport use and these include long waiting times, transfer times and congestion on roads leading to work places. In conclusion, modal choice is influenced by the characteristics of the traveller, the characteristics of the transportation system (including costs) and behavioural factors that include human perception about particular modes of travel. Recommendations are that the city authorities of Harare need to study travel behaviour also using travel models so as to come up with a viable transportation system. More efficient travel modes such as a train shuttle service and affordable commuter buses need to be introduced in the city and these should involve as minimal transfer as possible.
