Analysis of ground access modes choice King Khaled International Airport, Riyadh, Saudi Arabia

Airports are vital to the transportation system because air travel is the fastest means of transporting people and goods around the world. Airports also connect aviation systems with other modes of transportation.As a result, access modes to airports are critical to the aviation system, and studying air passenger decisions regarding mode choice is an essential part of airport management and system planning.Though there has been systematic analysis of car use to access airports, there has been less systematic attention to the use of the public transport system, especially the taxi service. The aim of this study is to identify King Khaled International Airport (KKIA) access mode characteristics and users, which has not been investigated previously concentrating on the mix between car and taxi using data collected specifically for this research.More than half (55.5%) of the travelers surveyed arrived at KKIA by private car; taxi and limousine passengers accounted for 42.2% of the sample. The Saudi Public Transit Company (SAPTCO), transported only 2.3% of the air passengers surveyed. These results are similar to findings for an airport in the United States and very different from findings for an airports in the East (e.g., Hong Kong).A binary logit model was developed to evaluate the access mode choice. It was found that income, luggage, travel access time, and nationality significantly affect mode choice.Results provide insight for improved planning of access to KKIA.     

Bus quality partnerships,modal shift and traffic decongestion

A more sustainable transport system requires effective alternatives to private cars. Despite more than 40 years of declining use, buses are still the main form of local public transport outside central London. Government policy focuses upon Bus Quality Partnerships—agreements between highway authorities and bus operators to give bus priority access and invest in better quality buses—to reverse this decline and also attract car drivers to change modes and ease urban traffic congestion.This paper assesses the potential for Quality Partnerships to provide a more attractive bus service with the ability to achieve modal shift using a Greater Manchester case study. Preliminary results are presented from a comparative study of two Quality Bus Corridors (QBCs), one arterial route into Manchester’s Central Business District and one transverse from Leigh to Bolton. The research uses bus user interview surveys and in-depth interviews, which focus upon non-bus users.Results of this research show that Bus Quality Partnerships when introduced as a stand-alone policy struggle to achieve significant modal shift and traffic decongestion. Most bus passengers and car users remain unaware of Bus Quality Partnerships.     

Helping drivers out of their cars Integrating transport policy and social psychology for sustainable change

Which motorists are ready to reduce their car use and how should they be helped to change? Results are reported from a postal questionnaire survey study of English car drivers (N=791). One third (33%) of car drivers indicated they would like to reduce their car use ‘over the next 12 months’, but only 7% thought they were likely to. One third (34%) of car drivers would like to use public transport (PT) more, but only 5% thought they were likely to. While over one third anticipated changes in their transport mode usage, and 1 in 5 (19%) would like to both decrease car use and increase PT use, only 3% thought this combination likely. Effectiveness ratings of pull and push policy measures showed motorists would rather be pulled than pushed from their cars; that the old, the poor and urban dwellers would be more susceptible to push measures; and that those residing out-of-town, driving medium and large cars, driving high annual mileage and required to drive as part of their work are less likely to be persuaded to reduce their car use by either type of measure. Other social psychological research suggests that sustainable changes by individuals that can be integrated into individual patterns of life will be more readily achieved by facilitation and support than by coercion.     

Factors affecting airport access mode choice for elderly air passengers

This research investigates whether elderly air passengers exhibit different mode choice behavior in regard to airport ground access. Using survey data from a Taiwanese sample, our results show that elderly air passengers prefer to ask family members to drive them to the airport, while general passengers prefer to take a taxi. The results also indicate that “safety” is the most important item in the choice of access mode and “user friendly” and “convenience for storing luggage” as the next most important items for the elderly. Elderly passengers are found to be less likely to use public transport than private transport. Factors such as “possessing a car in their household”, “carrying more luggage”, “spending more time spent in the vehicle”, and “higher ticket prices for public transport” increase the propensity for the elderly to use private transport.     

Impacts of vehicle restrictions on urban transport flows: The case of Santiago,Chile

Regression models are employed to quantify the effects of vehicle restrictions on private and public transport passenger flows in Santiago, Chile using trip flow data for cars, buses and the city's Metro rail system. Estimates are derived for the effects of two restrictions: a permanent measure applied from April through August 2008 to vehicles without catalytic converters and additional measures that banned the use of vehicles with catalytic converters between 7:30 am and 9 pm on days declared as environmental “pre-emergencies” due to high air pollution levels. The estimates show that the permanent restriction had no impact on the use of private cars while the additional restriction curtailed their use by 5.5%. Also, on pre-emergency days the flow of passengers to the Metro increased by about 3% while the bus network showed no statistically significant increase. The pre-emergency restrictions thus had an effect on the ridership of the Metro but not on the bus network as alternatives to the use of private cars.     

Attitudes towards traffic problems and public transport in the Dartmoor and Lake District National Parks

Problems associated with traffic demand have received only scant attention in the rural context and, although accepted as a viable approach to ameliorating urban traffic problems, traffic demand management has only recently been adopted by rural policy makers. In the national parks, where traffic-related problems are particularly acute, most traffic management measures are of the ‘carrot’ varity where attempts are made to persuabe private car passengers to use public transport transpon mobes, their success depends on tne attitudes of private car users towards public transport alternatives and their perceptions of the presence scale and impact of traffic-related problems. By analysing surveys of 768 drivers hr the Entamoor and Lake District National Parks, the potential success of ‘carrot’ measures is assessed and the implications for future policy addressed.     

Airport–airline interaction: the impact of low-cost carriers on two European airports

This paper uses case studies to look at the impact of low-cost airlines on two European airports. Low-cost airlines continue to exert an influence in air transport markets and small airports face pressures to compete for their business. The low-cost model motivates airlines to negotiate contracts that significantly reduce aeronautical revenues, leaving airports to compensate by seeking commercial revenues from the increase in passengers. This has consequences for the airports, their passengers and the relationship between the airport and its existing operators. It is found that it is important for airport management to see both passengers and airlines as customers and to understand the resultant revenue streams, before negotiating preferential contracts with low-cost carriers.     

The transformation of urban transport in the Czech Republic, 1988–1998

Similar to virtually all formerly socialist countries in Central and Eastern Europe, the Czech Republic has been experiencing a transport revolution since the shift from socialism to capitalism a decade ago. From 1988 to 1998, per-capita car ownership rose by 63% in the country as a whole, and by 93% in the capital city of Prague. Vehicle km of motor vehicle use have more than doubled. Conversely, public transport usage has fallen considerably, by 26% in the country as a whole, and by 19% in Prague. This modal shift from public transport to the private car has resulted from increased incomes, access to Western markets, declining real prices of cars and petrol, removal of restrictions on manufacturing and importing cars, and the car's attraction as a symbol of freedom, affluence, and status. The sharp reduction of subsidies for public transport has forced increases in fares and service cutbacks, which have also encouraged the shift toward the private car. Although the private car is very popular, the sudden surge in car ownership and use has caused significant social and environmental problems: roadway congestion, parking shortages, increased traffic accidents, air pollution, and noise. Given their severe financial limitations, Czech cities are struggling to preserve their public transport systems while accommodating the immensely popular private car.     

Factors of electric vehicle adoption: A comparison of conventional and electric car users based on an extended theory of planned behavior

Increasing the share of battery electric vehicles (BEV) in the total car fleet is regarded as a promising way to reduce local car emissions. Based on online surveys in Denmark and Sweden, this study compares BEV users' (n = 673) and conventional vehicle (CV) users' (n = 1794) socio-demographic profiles, attitudinal profiles, and mobility patterns. In line with previous research, BEV users are typically male, highly educated, have high incomes, and often more than one car in their household. Additionally, BEV users perceive less functional barriers toward BEV use and have more positive attitudes and norms than CV users. The different profiles of these user groups suggest a separate analysis of potential factors of BEV adoption in both groups. In regression analyses, CV and BEV users' intention to use/purchase a BEV is modeled based on factors of the Theory of Planned Behavior extended by personal norm, perceived mobility necessities, and BEV experience. For CV users, symbolic attitudes related to BEVs are the most important factor of intention, while perceived functional barriers in terms of driving range are most relevant for BEV users' intention. How BEV users cope with trips of longer distance seems of particular relevance. In multiple car households, we found the percentage of actual BEV usage related to the type of other cars in the household, perceived functional barriers of BEVs as well as (successful) behavioral adaption to longer trips by BEVs. Based on the results, we discuss ways to increase BEV adoption for current users and non-users.     

Brazilian airport economics from a geographical perspective

This paper discusses the revenue and expenditure functions of a sample of Brazil’s airports administered by Infraero, the Brazilian State enterprise responsible for administering the country’s major airports. It aims to identify what volume of movement at the airports associates with positive net earnings, i.e., the break-even point between revenue and expenditure, in view of aspects of airport movement and geographical factors. It examines airports serving regular airlines and with movement of up to 8 million passengers in 2010. Revenues and expenditures are explained by total passengers embarked and disembarked at each airport and by the potential of the airport’s ‘anchor city’. Multiple regression analysis achieved a high level of explanation for the dependent variables studied, i.e., revenues and expenditures. The model explains 81% and 91% of the variations in revenues and expenditures, respectively. The analysis shows that, considering the ranking of cities, Brazilian airports with less than 2 million passengers tend to operate at a financial loss, those with between 2 and 3 million passengers are at the transition stage between positive and negative earnings, while airports with more than 3 million passengers tend to make gains. However, the simulation modelling shows that the break-even point between expenditure and revenue functions can vary considerably when different ‘city potentials’ are considered. In this respect, the modelling offers investors a tool for analyzing passenger demand risk in the light of expectations for Brazilian cities’ potential.     

Strategic travel planning toward future emission targets—A comparative analysis of 20 Swedish municipalities applying the CERO model

Organizations displaying best practices for attaining proactive sustainability targets at local level are of major importance as role models in the transition toward a sustainable transport system. This study summarizes results and conclusions from 20 municipalities in Sweden that have implemented the so called CERO analysis in order to adapt to future emission targets for travel. The overall aim of the study is to identify factors explaining why some municipalities are more successful than others in a benchmarking comparison.

The results indicate that commuting by car is by far the most dominant source of emissions, constituting on average 76% of total annual travel emissions (including both commuting and business travel). In order to reduce these emissions, travel planning programs within organizations must address both commuting conditions and business travel conditions to reduce car dependence for work travel, e.g., employees using private cars for business trips most likely also use their own cars for commuting. To identify potential success factors as regards emissions-efficient travel, three comparative statistical analyses were conducted: grouping municipalities with low emissions in relation to the total average; analysis of car commuters' willingness to change travel mode; and before-and-after analyses of municipalities implementing specific action plans. The results revealed that municipalities conducting follow-up studies 2 years after implementing travel planning programs all lowered their total CO₂ emissions, by on average 10% during a 2-year period. Overall, these municipalities achieved redistribution to alternative travel modes but also reduced total travel mileage.     

Living “up in the air”: Meeting the frequent flyer passenger

This paper uses a large database of approximately 37,000 passengers and three different estimates to analyse the characteristics of the frequent flyer and the differences between frequent flyers and occasional flyers. The results show that frequent flyers are middle-aged men with a high level of education who take domestic flights for business reasons at both hub and regional airports, where they make a purchase and/or consume F&B. Frequent flyers fly on both low-cost and traditional airlines, are more likely to stay overnight at a relative's or friend's home and travel to the airport by private or rented car.     

Intermodal integration in air transportation: status quo, motives and future developments

Soaring air traffic, increasing urban expansion and airports operating at full capacity are reasons that have caused a discussion about improvements in airport landside access systems. One approach to better match customer demands and address airport congestion is to facilitate the intermodal integration of airports. Building on a survey on intermodal passenger air transportation, we elaborate on the current and future situation at major airports. Our findings indicate a high modal concentration and dependence on individual access modes. However, while airport managers intend to reduce the share of these modes, they plan to increase that of high-occupancy airport access modes. We analyze the underlying motives that cause airports to extend their connections to surface infrastructure. In a case study, we assess an intermodal best practice solution for the integration of air and rail.     

An econometric analysis of domestic air traffic demand in regional airports: Evidence from India

The Indian aviation industry has a vast potential to grow to cater to its population and commerce through developing air transport services to the regional airports. This paper examines the possible determinants of domestic air traffic demand in Indian regional airports serving below three million passengers per annum. Using multiple regression analysis, we find that distance to the nearest airport and accessibility of the airport significantly affect traffic volumes in regional airports. This study also highlights the specificities of Indian regional airports.     

Car parking management at airports: A special case?

The number of employees who daily commute to an airport represents, on average, one quarter to one half of the daily number of passengers. At UK airports it is rare for employees to pay for their car parking, with most employers absorbing the charges imposed by the airport authority. This paper details the main issues with offering free parking to employees drawing comparisons between a selection of case studies where parking management measures for employees have been introduced, and the airport sector. The paper then reports on a survey and a series of focus groups that were conducted with employees at a large UK airport in order to gauge their attitudes and likely behavioural responses to potential parking management strategies. Key findings are presented to show how airports may be able to learn from the experiences of others in the successful introduction of parking management strategies, but that there are also key barriers that are specific to airports that would need to be overcome.     

Predicting the impact of Trans Java Toll Roads on demand for intercity air travel in Indonesia

This paper aims to explore the factors influencing a potential air passenger shift to autos due to the completion of the Trans Java Toll Road and an increase in airfares. The study focuses on intercity trips for nonbusiness purposes. A face-to-face interview survey of 751 air passengers was conducted in three main airports on Java Island, Indonesia. Both the theory of planned behavior and the discrete choice model were applied to understand the factors for influencing toll road use among air passengers. The empirical results reveal that psychological factors, consisting of attitudes, subjective norms, and perceived moral obligations significantly influenced intentions to use the toll road. Meanwhile, perceived control of external resources was essential for airline passengers in their intention to use toll roads. Sociodemographic factors such as age, gender, income, frequency of airplane use, travel time, and cost also significantly influenced the decision to drive. Female, older passengers, high-income passengers, and frequent flyers were more likely to continue flying. The finding confirms that the Trans Java Toll Road affected a decline in air demand on Java Island. However, traveling with family members, rather than airfare hikes, became a more substantial reason for air passengers to switch to driving the toll roads. This research found that air passengers were inelastic related to changes in travel time, while 6% were willing to switch due to airfare increases of 10%.     

Offsite passenger service facilities: A viable option for airport access?

Offsite passenger service facilities transfer passengers from a common location to an airport and may provide additional services such as baggage handling and passenger check-in. Although they are conceptually promising, there is a lack of modern methods specifically tailored to forecast their demand. This paper reports on the development of two sequential models that forecast demand for an offsite facility. Models were calibrated based on data collected at six airports in California, Maryland, Massachusetts, and Virginia. The results showed that likely candidates for an offsite facility are airports that are not easily accessible, and departing air passengers with early morning flight departure times and high variability in ground travel times to the airport. A case study demonstrates the application of the models to Virginia’s Richmond International Airport.     

An examination of the effects of ride-hailing services on airport parking demand

The emergence of ride-hailing services offered by the Transportation Network Companies (TNCs) globally are substantially affecting how we travel by car, and as such, use parking facilities. Airport parking, which is a substantial source of revenue for the airports, is no different and anecdotal evidence suggest a reduction in parking revenue in airports in recent years as a result of the popularity of ride-hailing services. This research investigates the effects of the entry of ride-hailing services on airport parking patronage using three large airports (John F Kennedy International, Newark Liberty International and LaGuardia) in the US as a case study. Intervention analysis technique was used on time-series monthly parking data at these airports, controlling for passenger numbers. Results indicate there was a statistically significant reduction in the numbers of cars parked at all three airports since the introduction of ride-hailing services, confirming the anecdotal evidence. Findings have implications not only for airport business and revenue models, but also for wider effects of ride-hailing and automation.     

Air deregulation in China and its impact on airline competition 1994–2012

China’s air transportation has experienced rapid growth and major reforms in the past three decades, some of which have been partially successful and are still ongoing today. The paper aims to analyze China’s air deregulation experience over the last two decades and its impact on airline competition from a geographical perspective. After the establishment of the “Big Three” in 2002, the paper reveals that there has been a trade-off between the extent of deregulation and airline competition in China because the central government has tended to strengthen the “Big Three” rather than totally open the market to private and locally owned airlines. The paper uses each airline group as the basic unit of analysis and reveals that (1) the air market has been more concentrated in the “Big Three” as a result of the process of air deregulation; (2) airline competition in over two thirds of the airports and one half of the routes has increased in the last 18 years, but the core airports and trunk routes are chiefly dominated by the “Big Three”. The peripheral airports and thin routes have been operated by private and locally owned airlines; and (3) regionally, airline competition has occurred in most airports of the eastern region, and it is more intense than in the central and western regions. But even here, competition in the eastern region has however decreased in 1994–2012. The three main contributions of the paper are: (1) the use of two measures of competition in the airline market; (2) the analysis of the historical evolution of competition; and (3) an understanding the role of the geography of competition in the Chinese airline market.     

Airport privatization with public finances under stress: An analysis of government and investor's motivations

The management model of airports has long stood as a central research area in the transport sector. There are a wide range of studies that focus on the potential benefits and pitfalls of private airport management. The results of these efficiency studies have not provided irrefutable evidence for the superiority of private management over public management, but the momentum towards privatizing airports is growing. The reason for privatization has been more related with privatization revenues for governments, rather than more efficient management. The search for maximizing the sale value can have negative impacts from a welfare perspective, for example, through excessive increases in tariffs for passengers. This research reflects on the motivations for governments to privatize, and is illustrated by a case study – Portugal – in which the privatization occurred as a result of three main large drivers: 1) a bailout programme by the IMF, the EU, and the ECB; 2) a revision of the regulatory model, and; 3) the need to increase the capacity of Lisbon's airport system in the medium term.
