    Further development of SAMPERS and modeling of urban congestion2014Report (Other academic)
    Abstract [en]

    The need to more precisely represent the consequences of congestion mitigation policies in urban transport systems calls for replacement of the static equilibrium assignment by DTA in the integrated travel demand and traffic assignment models. Despite of the availability of DTA models and despite of the conceptual clarity of how such integration should take place, only few operational model systems have been developed for large-scale applications. We report on replacement of the static traffic assignment by two different DTAs in the four stage demand model for the Greater Stockholm region: the macroscopic analytic Visum DUE and microscopic simulation Transmodeler. First results show that even without systematic calibration the DTA is in reasonable agreement with observed traffic counts and travel times. The presented experiments did not reveal striking difference between using macroscopic and microscopic assignment package. However, given the clear trend to microscopic modeling and simulation on the travel demand side, the use of micro-simulation-based DTA package appears more natural from system integration perspective.

    The impact of travel costs and economic growth on cost-benefit analysis rankings2012Manuscript (preprint) (Other academic)
    Abstract [en]

    The use of Cost-benefit analysis (CBA) as a tool for selecting transport investments is often questioned. It is not unusual that politicians or others in the public debate argue that the outcome of a CBA completely rely on assumptions concerning a particular input factor, such as valuation of CO2 emissions or future fuel price. This paper explores whether the relative ranking of CBA outcomes are robust with respect to some key inputs in transport demand analysis driving cost, public transport fare and economic growth. We study six different infrastructure objects (three road and three rail objects) and four alternative assumptions on input factors compared to a reference scenario.

    The findings suggest that single input factors in a CBA, individually have a small impact on the ranking of the studied investments. In our model calculations we observe no change in rank between a road and a rail object.

    A dynamic discrete choice activitybased travel demand modelManuscript (preprint) (Other academic)
    Abstract [en]

    During the last decades, many activity-based models have been developed in the literature. However, especially in random utility based models timing decisions are often treated poorly or inconsistently with other choice dimensions. In this paper we show how dynamic discrete choice can be used to overcome this problem. In the proposed model, trip decisions are made sequentially in time, starting at home in the morning and ending at home in the evening. At each decision stage, the utility of an alternative is the sum of the one-stage utility of the action and the expected future utility in the reached state.

    The model generates full daily activity schedules with any number of trips that each is a combination of one of 6 activities, 1240 locations and 4 modes. The ability to go from all to all locations makes evaluating the model very time consuming and sampling of alternatives were therefore used for estimation. The model is estimated on travel diaries and simulation results indicates that it is able to reproduce timing decisions, trip lengths and distribution of the number trips within sample.

    To explain when people perform different activities, two sets of parameters are used: firstly, the utility of being at home varies depending on the time of day; and secondly, constants determine the utility of arriving to work at specific times. This was enough to also obtain a good distribution of the starting times for free-time activities.

    The long term social benefits of transit2012Conference paper (Refereed)
    Abstract [en]

    Standard CBA is often criticised for not taking land use effects induced by transport investments and wider economic benefits into account. The purpose of this paper is to estimate the size of these effects using the Stockholm Metro built in the 1950’s, the largest urban rail investment in Sweden, as a case study. We find that benefits of the Metro increase 60 percent due to long term land use adjustments. Wider economic benefits increase the benefit by 17 percent.We show that the Stockholm Metro was socially beneficial to build according to present standard methods, even without taking land use effects and wider economic benefits into account. Hence, the anecdote that the Metro of Stockholm had not been built if CBA had been a part of the appraisal seems to be false.

    The long term social benefits of urban transit investments: A CBA of the Stockholm Metro2012In: Kuhmo Nectar Conference and SummerSchool on Transportation Economics 2012 -Annual conference of the ITEA: Book of Abstracts, 2012, p. 131-132Conference paper (Refereed)
    Abstract [en]

    Cost Benefit Analysis (CBA) has been a fundament of appraisal in Northern European Countries for decades and is becoming increasingly important in Sweden (Eliasson and Lundberg, 2011). Still, the CBA methodology is a relatively young tool and has been developed for evaluation of smaller infrastructure objects. Also proponents of the CBA method recognise some methodological problems (see for instance Mackie and Preston (1998)), in particular of large infrastructure investments. Uncertainty in CBA outcome was recently discussed by the OECD Forum for infrastructure issues, International Transport Forum. To undermine the trust in CBA as an accurate decision support, it is often stated in the Swedish debate that the Stockholm Metro, build in the 1950’s and now central for the functioning of the traffic system and commuting, would not have shown a positive CBA outcome if the present methods and tools had been available at the time. The purpose of this paper is to perform an ex-post cost benefit analysis of the Metro system, the largest urban rail investment in Sweden. The Stockholm Metro has a track length of 105 kilometres, of which 62 kilometres are in tunnels, with a total of 100 stations spread over three lines. The application of CBA to an investment of the size of the Stockholm Metro illustrates clearly that there are certain benefits that may not be sufficiently well captured in standard CBA: land-use benefits, labour market benefits and benefits arising from increased capacity in the road and public transit network. In this paper we try to assess the size of the external labour market effects and land-use effects in the Stockholm Metro case.

    Land-use impacts in transport appraisal2014In: Research in Transportation Economics, ISSN 0739-8859, E-ISSN 1875-7979, Vol. 47, p. 82-91Article in journal (Refereed)
    Abstract [en]

    Standard cost-benefit analysis (CBA) does not take into account induced demand due to relocation triggered by infrastructure investments. Using an integrated transport and land-use model calibrated for the Stockholm region, we explore whether this has any significant impact on the CBA outcome, and in particular on the relative ranking of rail and road investments. Our results indicate that induced demand has a larger impact on the benefit of rail investments than on the benefit of road investments. The effect on the relative ranking is still limited for two reasons. First, the number of houses that are built over 20 30 years is limited in comparison to the size of the existing housing stock. Second, the location of most of the new houses is not affected by any single infrastructure investment, since the latter has a marginal effect on total accessibility in a city with a mature transport system. A second aim of this paper is to investigate the robustness of the relative CBA ranking of rail and road investments, with respect to the planning policy in the region 25 years ahead. While the results suggest that this ranking is surprisingly robust, there is a tendency that the net benefit of rail investments is more sensitive to the future planning policy than road investments. Our results also underscore that the future land-use planning in the region in general has a considerably stronger impact on accessibility and car use than individual road or rail investments have.

    An ex-post CBA for the Stockholm Metro2014In: Transportation Research Part A: Policy and Practice, ISSN 0965-8564, E-ISSN 1879-2375, Vol. 70, p. 135-148Article in journal (Refereed)
    Abstract [en]

    This paper performs an ex-post cost-benefit analysis (CBA) of the Metro system in Stockholm built in the 1950s. We find that the Metro was socially beneficial and that the largest benefit of the Metro is its capacity, making it possible for many people to travel to and from the city center. We also assess the significance of the wider economic impacts due to labor market distortions and the land-use effects in the case of the Stockholm Metro. The wider economic impacts increase the consumer surplus with 48%, and the yearly income in the county with 1.5%. A land-use model is used to simulate how the land-use has been influenced by the Metro over the years 1956-2006. This simulation indicates that the historical centralized planning of housing along transit corridors has developed the region into a more dispersed region than if the market forces had ruled. The simulation also suggests that the land-use impact from the investment itself is small, but that the land-use impact from the planning accompanying the decision to build the Metro has been substantial.

    The Usefulness of Transport Models in Swedish Planning Practice2011In: Transport reviews, ISSN 0144-1647, E-ISSN 1464-5327, Vol. 31, no 2, p. 251-265Article in journal (Refereed)
    Abstract [en]

    This paper presents some experience from using transport models in Swedish planning practice. First we outline three recent examples of planning settings in which transport models have been put to extensive use. For the Swedish ‘national’ transport plan for the period 2010–2021, which was recently finished, the national transport model SAMPERS was used to compute costs and benefits for many investment projects. The second example concerns the ‘regional’ plan for Stockholm, where a similar but less detailed model, LuTRANS, was used to investigate different transport and land use scenarios. The third example discusses a recent study on the feasibility of introducing congestion charges in Gothenburg, where both a fixed demand approach and SAMPERS were used. Furthermore, the paper tries to help identify what model development can do to help improve the production of decision support through modelling. We argue that effectiveness and efficiency are key. The first is characterized by making sure that the right things are done and that they are done right. Efficiency, which is less often discussed in the literature, is framed in terms of doing things on time and doing them only once. The managing organization around a national model system can play an important role in helping users avoid redundant work. It is also a good idea to resist the temptation to use up all improvements in computing power for additional model features. There are many worthwhile analyses that are never done because of time constraints.

    Abstract [en]

    This paper presents a dynamic discrete choice model of activity scheduling that features classic time-geography properties within a microeconomic framework. We present results that show how the model can produce accessibilities that form space-time prisms, while retaining the properties of traditional measures based on consumer surplus in the form of logsums. The main features of the model are that it handles time-space constraints, travel time uncertainty, and endogenous trip chaining in one consistent framework. The resulting accessibility respects the individual's time budget and fixed activities. The dynamic discrete choice framework makes possible estimation of behavioural parameters using well-known methods. Some of the remaining computational challenges are discussed. The final section provides some examples of the policy analysis possibilities provided by a model of this kind.

    Analysing sustainability in a land-use and transport system2008In: Journal of Transport Geography, ISSN 0966-6923, E-ISSN 1873-1236, Vol. 16, no 1, p. 28-41Article in journal (Refereed)
    Abstract [en]

    In this paper we investigate some implications of including intergenerational fairness when appraising the impact of transport policy on an urban land-use and transport system. The paper also reports on the implementation of an appraisal framework where the main elements of sustainability is taken into account. The land-use and transport system of Stockholm is modelled using the land-use model IMREL, paired with the state-of-the-art transport model SAMPERS.The intergenerational fairness is handled by modifying the normal exponential discounting of a cost–benefit analysis. We form the weighted sum of a normal cost–benefit analysis and the horizon year costs and benefits without discounting. The relative weight put on each term is governed by an intergenerational parameter, α. What we do is let the undiscounted horizon year represent the long term future, so setting α = 0 means using an ordinary exponential discount rate. α = 1 on the other hand puts all weight on the long term future, ignoring costs and benefits for the years up to the horizon year. We experiment with some values of the intergenerational parameter to see how it affects the ranking of combinations of two policy instruments.Optimisation is employed to further analyse the implications of using combinations of instruments. A problem that arises when packaging instruments into strategies is that the number of possible combinations gets large. Optimisation can be of use to find the interesting ones. Our modelling package is fairly detailed, which means long computations, and generally not suited for automated optimisation. Instead we use a response surface method, where the objective function is approximated with a quadratic function, which is fitted to model computed values of the objective function by regression.

    Analysing Sustainable Urban Transport and Land-Use: Modelling tools and appraisal frameworks2008Doctoral thesis, comprehensive summary (Other scientific)
    Abstract [en]

    Sustainable development and climate change is high on the agenda for most cities around the world today. Urban transport is at the heart of these changes. Increasingly, it is recognised that not only is the emission of pollutants and greenhouse gases a problem, but also the detrimental effects of congestion and social exclusion. In order to address these issues, it will be necessary for cities to make strategic long term decisions regarding the future infrastructure and land use, not only in terms of what will be built, but also on measures that affect how these systems are used.This thesis is focused on the decision support tools that we need in order to make well informed decisions. Models that predict the performance of future scenarios, and appraisal frameworks that help evaluate whether these outcomes are desirable or not. The first two papers experiment with different ways of bringing some aspects of sustainability into the appraisal frameworks used to analyse long term strategies. Paper I addresses intergenerational fairness, and Paper II focuses on the emission of greenhouse gases. Paper III develops a model, Scapes, that can help us to better understand the daily travel behaviour, through an activity based approach. By explicitly modelling space-time constraints, and travel time uncertainty in a microeconomic framework, we can get a better understanding of how people can respond to, and value, changes in the transport system. Papers IV and V describe a new integrated land use and transport model, LandScapes.The policy implications from the studies in Papers I, II, and V are that it will be very difficult for Stockholm to reduce its emissions of CO2. Particularly, predicted economic and population growth will inevitably lead to more transport. It is likely that a range of different policies will be necessary to solve that problem. At the same time, we must not forget that decreasing CO2 emissions, although important, is not the only objective Stockholm has. To cope with the increasing travel demand from a growing population, it may well be necessary to build new infrastructure as well. This thesis does not prescribe any such relative valuation between conflicting objectives. It only helps bring them to the fore.

    User attitudes towards a corporate Mobility as a Service2018Manuscript (preprint) (Other academic)
    Abstract [en]

    Mobility as a service (MaaS) envisages enabling a co-operative and interconnected single transport market which provides users with hassle free mobility. Among MaaS postulated benefits, MaaS enthusiasts claim that MaaS solutions could persuade people to give up their car. Conversely, there is a fear that MaaS could in fact induce less sustainable travel, by means of inducing extra demand, and even attract current public transport users towards taxi and car-pool alternatives.

     

    In this study we investigate user attitudes and expectations towards a corporate MaaS solution, through a latent class and latent variable model. Results support that there is a trend from car ownership to usership. We also find no evidence that MaaS solutions could produce a shift from public transport users to other less space-efficient shared-mobility solutions such as taxis or car-pool alternatives under our experiment conditions. In connection with user’s preference to share a car journey with strangers, we find the existence of two opposite trends. This finding suggests that there might be appetite for both types of solutions, where users could choose between private or shared journeys by car. Moreover, we find that normative beliefs impact user mobility styles, and that the need and feeling for flexibility is found to be one of the key factors for users to embrace a MaaS solution.

    Urban ecosystems and sustainable urban development-analysing and assessing interacting systems in the Stockholm region2013In: Urban Ecosystems, ISSN 1083-8155, E-ISSN 1573-1642, Vol. 16, no 4, p. 763-782Article in journal (Refereed)
    Abstract [en]

    In order to build competence for sustainability analysis and assessment of urban systems, it is seen as essential to build on models representing urban form, landuse and transportation, urban metabolism, as well as ecological processes. This type of analysis of interacting sub-systems requires an advanced model integration platform, yet open for learning and for further development. Moreover, since the aim is to increase urban experience with ecosystem management in the wide sense, the platform needs to be open and easily available, with high visualisation capacity. For this purpose, the LEAM model was applied to the Stockholm Region and two potential future scenarios were developed, resulting from alternative policies. The scenarios differed widely and the dense urban development of Scenario Compact could be visualised, destroying much of the Greenstructure of Stockholm, while Scenario Urban Nature steered the development more to outer suburbs and some sprawl. For demonstration of the need for further development of biodiversity assessment models, a network model tied to a prioritised ecological profile was applied and altered by the scenarios. It could be shown that the Greenstructure did not support this profile very well. Thus, there is a need for dynamic models for negotiations, finding alternative solutions and interacting with other models. The LEAM Stockholm case study is planned to be further developed, to interact with more advanced transport and land use models, as well as analysing energy systems and urban water issues. This will enable integrated sustainability analysis and assessment of complex urban systems, for integration in the planning process in Stockholm as well as for comparative sustainability studies between different cities, with the goal to build more sustainable urban systems and to increase urban experiences in ecosystem management.

    Assessment of transport policies toward future emission targets: A backcasting approach for Stockholm 20302006In: Journal of Environmental Assessment Policy and Management, ISSN 1464-3332, E-ISSN 1757-5605, Vol. 8, no 4, p. 451-478Article in journal (Refereed)
    Abstract [en]

    Stockholm has set a target for greenhouse gas emissions in the year 2030, based on the United Nation's (IPCC) recommendations for an acceptable CO2 level in the atmosphere. In this study we use a backcasting framework to analyze a range of specific transport policies and fuel technology related developments with respect to the emission target. Our study employs a transport modelling system, traditionally used for forecasts, to quantify the impacts of various travel demand measures (TDM). Our study shows that the change in travel demand, induced by various travel policies, will not suffice on its own to reach the target. Even if fuel price is tripled, a substantial share of renewable fuels is required for target achievement. While our study shows that travel demand measures have a fairly small effect on CO2 emissions, it also hints at other compelling reasons for introducing such measures. Constructive strategies for the transport system would not only contribute to reduce risks with climate change. Even small reductions of transport volumes might imply large socio economic savings in traffic related costs, reduced emissions of substances with health impacts, fewer accidents, shorter travel times and higher travel time reliability. These aspects are arguably all part of a sustainable transport development.
