Evaluating the long-term impacts of bus-based park and ride

Many park and ride (P&R) schemes worldwide are based on rail transport, however there has also been substantial development of bus-based P&R in which an enhanced bus service operates between a P&R site and an urban centre. This has been particularly marked in Britain, often in historic cities (such as York, Oxford and Cambridge). Development of busways has also provided opportunities for complementary P&R development. Nonetheless, a net increase in passenger car unit (pcu)-kilometres may be observed, despite a reduction on the principal radial corridor. This is due to increased car-kilometres in catchment areas of P&R sites, but this simple additive approach to changes in pcu-km may not reflect overall impacts if pcu-km are removed from a congested urban corridor. By using monetised external cost per pcu-km for different road types and traffic conditions (such as those in ‘WebTAG’ guidance in Britain), the net effect can be expressed in economic terms. Presented here is a case study of the Chelmsford system, showing that a net economic benefit may be attained, even though a net increase in pcu-km has occurred. Energy savings through diversion of car occupant trips to the Cambridgeshire busway are also assessed

Business models in rail infrastructure: explaining innovation

Policy decisions about the UK railway industry often draw on models and frameworks that treat technology and organisational processes as static and unchanging. As a result, policy makers often have limited understanding of how changes in policy will influence organisational knowledge, learning and the allocation of risk that subsequently affects innovation and system development. This paper applies a business model lens, focused on the mechanisms firms use to create and capture value, to connect policy decisions to subsequent changes in the organisation and industrial structure of the UK railway sector. By analysing innovation-related activity across several different governance structures, the paper highlights how policy impacts in network-based infrastructure sectors are mediated by business strategy, sometimes leading to unintended outcomes. The findings suggest that policy to improve the performance should focus upon coordination rather than just ownership. The application of a business model approach to complement existing economic and policy models in system analysis for policy decisions is advocated

Sustainable travel behaviour and the widespread impacts on the local economy

Statistics show that unsustainable travel behaviour and global greenhouse gas emissions are growing and due to the perceived indispensable nature of personal travel, shifts to more sustainable modes remain a challenge. Automobility supports sustained local economic growth but also raises issues around safety, health, road fatalities, traffic and congestion, and detrimental environmental impacts. This article addresses the issue of sustainable mobility by investigating how to increase sustainable travel choices and, where this is not possible, ensure existing travel choices and patterns are as environmentally friendly as possible. Existing soft initiatives aimed at increasing sustainable travel behaviour fail to fully acknowledge that travel decisions are made at the individual level and that tailored strategies would be more effective at targeting distinct behavioural patterns. Influencing changes in travel behaviour at the local level demonstrates significant potential where individual behaviour can be influenced if appropriate support at the system level is in place and complies with the needs of individuals. This article demonstrates that, in doing so, this will simultaneously address other areas, such as accessibility, employability, health and sustainable growth, crucial to the establishment and survival of automobility by both supporting local economic growth and achieving reductions in carbon emissions

The Journey Experience of Visually Impaired People on Public Transport in London

The use of public transport is critical for Visually Impaired People (VIP) to be independent and have access to out-of-home activities. Despite government policies promoting accessible transport for everyone, the needs of VIP are not well addressed, and journeys can be very difficult to negotiate. Journey requirements can often differ from those of other categories of people on the disability spectrum. Therefore, the aim of this research is to evaluate the journey experience of VIP using public transport. Semi-structured interviews conducted in London are used. The results show that limited access to information, inconsistencies in infrastructure and poor availability of staff assistance are the major concerns. Concessionary travel, on the other hand, encourages VIP to make more trips and hence has a positive effect on well-being. The findings suggest that more specific policies should be introduced to cater to the special needs of particular disabilities rather than generalising the types of aids available. It is also concluded that the journey experience of VIP is closely related to an individual’s independence and hence inclusion in society

Policy making under uncertainty in electric vehicle demand

The introduction of electric vehicles (EVs) into the passenger vehicle market has, in recent years, become viewed as a primary solution to the significant carbon dioxide emissions attributed to personal mobility. Moreover, EVs offer a means by which energy diversification and efficiency can be improved compared to the current system. The UK government and European Commission have played an active role in steering the development and market introduction of EVs. However, a great deal of uncertainty remains regarding the effectiveness of these policies and the viability of EV technology in the mainstream automotive market. This paper investigates the prevalence of uncertainty concerning the demand for EVs. This is achieved through the application of a conceptual framework that assesses the locations of uncertainty. UK and EU documents are assessed through a review of the published policy alongside contributions from academia to determine how uncertainty has been reduced. This assessment offers insights to decision makers in this area by evaluating the work done to date through a landscape analysis. Results have identified six different locations of uncertainty covering: consumer, policy, infrastructure, technical, economic and social issues

Markets, large projects and sustainable development: traditional and new planning in the Thames Gateway

The transition from traditional hierarchical government to new forms of governance and planning can be overstated. The regionalisation of planning and new ambitions for spatial planning in the UK are commonly understood to have created an overcomplex system concerned with co-ordination and integration across jurisdictional spheres. However, this new governance of planning sits alongside traditional planning processes such as the public inquiry and ministerial decision. This case study of a large port development near London suggests that the emphasis upon the move to new, collaborative practices understimates the influence of traditional governmental structures. This provides cause for questioning the capacity of the current planning system to address the challenge of sustainable development, a central concern for the new planning

Autonomous vehicle interactions in the urban street environment: A research agenda

© ICE Publishing 2018. All rights reserved. The Venturer project is trialling an autonomous vehicle (AV) in the context of use on urban roads. This paper summarises a literature review undertaken to assist in developing a research agenda for the trialling. The first contribution of the paper is a framework of four use scenarios for AVs as follows: (1) fully segregated AV network, (2) motorway or expressway network, (3) typical urban network, (4) shared space. The paper then focuses on a review of the social interactions in the street environment and discusses issues concerning human behaviour in relation to autonomy. The second contribution of the paper is a set of research questions for AV trialling in relation to other road users, including, pedestrians and cyclists, which have emerged from the literature review.

Assessment of computer-based training packages to improve the safety of older people’s driver behaviour

Examination of police records in Wales (STATS19 database) suggests older drivers are over represented in collisions turning across traffic and those involving failure to look properly, failure to judge the other vehicle or person’s path and performing a poor manoeuvre. A convened expert group suggests this is due to changes in attention, cognitive overload, processing speed, perceptual speed, working memory, task switching and eyesight associated with ageing. Training using computer-based packages can improve these cognitive and physiological issues associated with age. Performance on Useful Field of View (UFoV), Delayed Recall, Maze test and Dual N task computer tasks have all been shown to be related to number of crashes older drivers have. Of these only UFOV and Dual N task training improvements have been demonstrated to translate into improved driver behaviour, but overall more research is needed

A highly successful model? The rail franchising business in Britain

A crucial feature of rail privatisation in Britain was franchising. Passenger services were franchised in competitive bidding processes to train operators which were meant to function with declining subsidy. The paper adopts the framework of social cost-benefit analysis to examine rail privatisation's impact on three key groups; consumers, producers and the government. It establishes that privatisation did not achieve all the supposed benefits. Further, franchising only appears to be profitable through the use of calculative accounting practices, where by franchised train operators are portrayed as discrete business entities, whereas they are supported by very substantial, ongoing direct and indirect government subsidies
