Abstract: | The paper analyses why CO2 emissions from heavy road freight transports increase in spite of higher fuel prices. Swedish time series data for the period 1990-2011 are analyzed with help of indicators. The logistic efficiency of the road transports improved especially in the 1990-ties due to the allowance of heavier trucks. Also the energy efficiency increased during that period. Since then there have been improvements but no major efficiency gains have been realized. Today potentially cost effective technologies exist to further reduce the CO2 emissions from heavy road freight transport. However, technical, institutional and financial barriers reduce the incentives for the transport firms to imply these. Split incentives caused by contract structures or ownership patterns can impede the employment of these technologies, as the firms that invest in the technologies have little incentive to do so. If fuel savings are realized rebound effects can appear that cancel out improved energy efficiency. The internalisation of the social marginal costs can lead to modal shifts to less carbon intensive modes, but shippers minimize their total costs and take into account quality aspects when choosing transport solutions. There are obstacles for the increase of the share of non-fossil energies in form of access to raw material, infrastructure for vehicles that can use the alternative fuels etc. On the national and international road freight transport markets staff costs are often more important than taxes and fees. Deeper knowledge of the impacts of different policy measures is required in order to understand why the CO2 emissions increase despite increased fuel prices. A better understanding of the implications of the lack of thresholds and other model simplifications in the Swedish Samgods model is also needed and an analysis of what is required to better mirror the contracts that we observe in reality. It is also necessary to study the role of the lighter trucks in the transport chains. |

Abstract: | Underpriced and overcrowded curb parking creates problems for everyone except a few lucky drivers who find a cheap space; all the other drivers who cruise to find an open space waste time and fuel, congest traffic, and pollute the air. Overpriced and underoccupied parking also creates problems; when curb spaces remain empty, nearby merchants lose potential customers, workers lose jobs, and cities lose tax revenue. To address these problems, San Francisco has established SFpark, a program that adjusts parking prices to achieve a target parking availability of one or two open spaces on each block. To measure how parking prices affected parking occupancy in San Francisco we calculated the price elasticity of demand for on-street parking revealed by 5,294 individual price and occupancy changes during the program’s first year. Price elasticity varies greatly by time of day, location, and several other factors, with an average value of –0.4. The average meter price fell 1 percent during the first year, so SFpark adjusted prices up and down according to local demand without increasing prices overall. The city can improve the program by making drivers more aware of the variable prices, reducing the abuse of disabled parking placards, and introducing seasonal adjustments for parking prices. |

Abstract: | This paper aims to unify concepts and to describe the multi-stage transport systems and their integratyion to supply chain management. Multi-stage distribution systems are common logistics management, and often they are assimilated to multi-stage transport strategies. However, transport is often considered as an external operation or a specific stage, even when it is a multi-stage system. First, the paper presents the main concepts of multi-stage transport systems by defining the concept an making a typology of transport schemes. Then, an optimization analysis using the concept of accessibility is proposed to show the advantages and limits of such strategies. Then, an interview-based analysis includes a conceptual framework for the integration of multi-stage transport on supply chain management and a simulation shows the impacts of multi-stage transport on supply chain global costs and quality indicators. |

Abstract: | Transport costs are widely considered an important barrier to local economic activity but their impact in developing countries is not well-studied. This paper investigates the role of inter-city transport costs in determining the income of Sub-Saharan African cities, using two new data sources. Specifically, it asks how important access to a large port city is for the income of hinterland cities in 15 countries. Satellite data on lights at night proxy for city economic activity, and shortest routes between cities are calculated using new road network data. Cost per unit of distance is identified by world oil prices. The results show that an oil price increase of the magnitude experienced between 2002 and 2008 induces the income of cities near a major port to increase by 6 percent relative to otherwise identical cities 500 kilometers farther away. Cities connected to the port by paved roads are chiefly affected by transport costs to the port, while cities connected to the port by unpaved roads are more affected by connections to secondary centers. These are important findings for economic development in Sub-Saharan Africa since the majority of its population growth over the next few decades is expected to be in urban areas. |

Abstract: | This paper addresses the lack of reliability within the Swedish rail network by identifying passenger train delay distributions. Arrival delays are analyzed in detail using data provided by the Swedish Transport Administration, covering all train departures and arrivals during 2008 and 2009. The paper identifies vulnerabilities by size, space and time in the network. Our results show that the delay distribution seems to be plagued by low probability high impact events. A major share of all delay time is associated with the tail of the delay distribution, indicating that extreme delays cannot be neglected when prioritizing between measures improving rail infrastructure. Delays are not only concentrated in size, but also concentrated in space and time and seem to follow a precise power law with respect to days and an exponential distribution with regard to stations. Moreover, we also examine the link between capacity usage and expected delay over different time scales. |

Abstract: | The aim of this paper is to describe the relationship between transport buying companies and carriers, with a focus on the transport contracts in Sweden for land based transports. Based on the aim of this study, the following research questions have been defined: How can contracts be categorized? What is the average duration and flexibility of the transport contracts to external changes? and Which environmental related elements are commonly regulated in the contracts? Based on a literature review and interviews with people on strategic positions in the transport industry, we have conducted a web-survey. In addition to contractual agreements the survey also tried to capture the relation on environmental issues, as well as the experienced logistics performance over time. Results from the survey indicates that the suggested contract categorisation from the literature was not well known by the respondents, the average duration of contracts was 1-2 years and the majority of contracts includes a fuel clause, but not many environmental requirements. Further, the analysis indicates that companies with long term contracts set environmental requirements to a larger extend and that there is a positive significant relation between the companies’ environmental work with in the transport operation and their perception of an improved logistics performance, both in terms of quality and cost. |

Abstract: | Some urban policies are designed to reduce auto and increase transit usage. Evidence is mixed because most empirical research uses ad hoc specifications. We estimate empirical models of the interaction between urban form and transit demand drawn from urban economic theory. Population density has a small impact on transit demand, which decreases when residential location is endogenous. Households living farther from work use less transit, a result of trip-chaining. Reducing the spatial allocation of non-work activities, improving transit accessibility at and around subcenters, and increasing the presence of retail locations in proximity to transit-oriented households would increase transit demand. |
