The growth of peri-urban areas is increasingly recognised as one of the dominant land use planning problems, with significance in the area of transport planning. This has necessitated the studying of travel behaviour in peri-urban areas in cities around the world. This study particularly examined the travel behaviour of households in the peri-urban areas of Ibadan, Oyo State, Nigeria. It used both primary and secondary data. The primary data were obtained through a field survey from the administration of questionnaires on household heads in the study area using a multi-stage sampling technique. Findings revealed that 21.5% of the variability in the travel behaviour among the respondents could be attributed to socioeconomic characteristics such as age, household size, and length of stay, the number of cars owned and monthly income of households. It is recommended that the socioeconomic characteristics of residents in peri-urban areas should be considered when making transport policies in the State.

Transport studies that adopt complex analyses present methodological challenges that lead to the use of innovative techniques to address the limitations of traditional methods. In the Latin American context, people consider security as a relevant variable in their daily lives. Thus, when people travel around the city and choose a mode of transport, security becomes an important factor and should therefore be included in transport studies. However, the definition of security in terms of transport in the Colombian context remains unclear. Therefore, we examined the security perception effect on transport mode choice by addressing security as a latent variable consisting of three elements: environment, subject and transport mode. We proposed the use of virtual reality (VR) to recreate travel routes and offer participants a scenario of choice closer to the natural conditions of a trip. The participants were provided routes in the form of immersive 3D videos recreating natural trip conditions to identify their choices and travel behaviour. Recordings were made of daily scenarios and existing urban environments portraying real and active modes of transport, giving respondents an almost-natural experience. The use of 360-degree immersive videos offers a multisensory experience allowing both the capture of socioeconomic and travel information and the collection of journey perception. The experiment evaluated two environments in Medellín, Colombia (secure (E1) and insecure (E2)) and studied the effects of lighting conditions (day (D) and night (N)). A total of four videos (E1D, E1N, E2D and E2N) depicting six transport modes in tandem were assessed by 92 participants from Medellín and Bogotá, Colombia. We found that environment-associated security perception varies depending on the time of the journey (day/night) and one’s familiarity with the environment. The research results position VR as a tool that offers high potential to support transport studies. We found that people’s movements, gestures and expressions while participating in the VR experiments resembled what was expected from journeys in reality. VR constitutes a relevant tool for transport studies, as it allows for an assessment of active transport mode perceptions. It prevents participants from being exposed to the risk associated with travel to specific places and carries out several routes in different transport modes even when participants cannot or have never undertaken journeys in the modes under assessment.

As transportation is an activity derived from spatial complementarities between a certain supply at an origin and a certain demand at a destination, according to a general axiom it seems that economic activities entail transport demand. In this perspective, an essential analysis deals with the quantification of the relationships between transport demand and certain socioeconomic variables. Elasticity is a concept widely used in transport economics as a measure of the responsiveness of transport demand concerning different factors represented as independent variables in an econometric model and coupling/decoupling concepts have been proposed in literature. This paper deals with the estimation of elasticities of motorway traffic demand based on Gross Value Added (GVA), and the consequent investigation of coupling/decoupling situation. The analysis is based on the application of an Autoregressive-Distributed Lag (ARDL) cointegration model with the F-bound test and of the related Error Correction model. Starting from the general ARDL model and the methodology for the verification of its robustness, the same model is applied to the Italian toll road network. The time series of GVA for goods and services and the overall length of the toll network from 1995 to 2019 are considered as explanatory variables of the total annual distance traveled by light and heavy vehicles. The various tests in the ARDL framework show a cointegration between the variables, under the fulfillment of all the diagnostic requirements. In this way, the long-term elasticities and the short-term adjustment dynamics are estimated separately for the goods and services components of GVA, and light and heavy vehicles. Starting from stable estimates of elasticities, the long-term coupling and decoupling effects between motorway traffic of light and heavy vehicles and the national production of goods and services can be shown. The paper, as well as providing an updated picture of the Italian situation, identifies a methodological framework that can be transferred to other contexts for a sector of great interest to investors, such as the motorway sector. All this can be useful to meet the needs of numerous stakeholders, who want to deepen the links between the economic cycle and traffic demand on toll motorways.

Transport Research Knowledge Centre (TRKC) is a project of the European Commission's Directorate General for Energy and Transport (DG TREN) and is funded under FP6. The primary aim of TRKC is to disseminate and promote the results of transport research activities at European and national level. It also illustrates how transport research programmes and projects help to develop guidelines and innovative tools to support European transport policy for sustainable mobility.

W artykule dokonano próby określenia kierunków i rodzajów badań transportowych realizowanych w ostatnim czasie, skupiając się na kilku obszarach geograficznych i tematycznych, a mianowicie na programach badawczych Unii Europejskiej, Stanów Zjednoczonych i Japonii. Odniesiono się też do oceny pól badawczych w szerokim kręgu międzynarodowym w oparciu o wyniki badań prezentowanych na Światowych Konferencjach Badań Transportowych.
