Comparing passengers’ satisfaction with fixed-route and demand-responsive transport services: Empirical evidence from public light bus services in Hong Kong

Conventional public transport services are usually highly regulated with fixed-route and fixed-schedule, which are considered less flexible and efficient to serve low-density and dispersed settled areas. Demand-responsive transport is possibly a more economically and operationally viable solution, which offers dynamically allocated routes and schedules and serve the widespread passenger demand. There have been numerous simulation studies comparing the effectiveness of these two types of transport services in different settings, but which type is more favorable to passengers and what service aspects play the key role in shaping the overall satisfaction with the service quality from the passengers’ point of view are largely unknown. Using fixed-route and demand-responsive public light buses in Hong Kong as a case study, this research conducted an on-street questionnaire survey with 547 samples regarding the passengers’ perception of the performance of ten service aspects and the overall performance. An ordered logit model was accordingly developed to identify the relative importance and contribution of these service aspects to the overall service quality. An importance-performance analysis was further carried out to visualize the ratings of importance and performance of the service aspects, and to prioritize the improvement areas. The findings reveal that the passengers were less satisfied with the demand-responsive public light bus services in general. Among all the service aspects, we find that the in-vehicle environment, waiting time, driver’s attitude, and safety hold a higher improvement priority. Policy implications for improving and regulating both fixed-route and demand-responsive public light bus services are suggested.

Measuring The Legal Consistency of Special Rental Transport Licensing

Special Rental Transport Arrangements, as one type of transportation of people with public motor vehicles on the road, are a response to the use of information technology as a medium of liaison between transporters and prospective passengers of public motor vehicles. But the arrangement does not place ASK complementary to other types of public transport services. The results showed that there was a different permit treatment between special rental transportation and transportation of people with public motorized vehicles not on other routes. The difference makes it easier for special rental transportation, compared to other types of transportation services. The difference is, first, the requirements for obtaining a license for a special rental transportation operator company, second, the condition that the vehicle must have proof of passing periodic tests, and third, the driver must have a General Driver's License. The norm of PM 118 of 2018 which provides the convenience (privilege) of licensing, is contrary to the norms of UULLAJ, PP Number 74 of 2014, and PM Number 117 of 2018. So that in fact, the norms of PM 118 of 2018 are void and non-binding because they conflict with legal norms that have a higher position, namely the norms of UULLAJ and PP Number 74 of 2014.

Safety System Assessment Case Study of Automated Vehicle Shuttle

Automated vehicle (AV) minibuses, i.e., AV shuttles, are gaining popularity in the testing of new types of transportation services in real traffic conditions. AV shuttles have moved from closed test areas to low-traffic public sites such as local residential areas, technology parks, university campuses, etc. These types of vehicles are usually low-speed and rely on a lidar-camera sensor set and a self-driving software stack. These new use cases are increasing these systems’ safety demands. In addition to functional safety, many other aspects need to be considered. In this study, a risk analysis model is developed, combining the fuzzy analytical hierarchy process and the Technique for Order of Preference by Similarity to Ideal Solution method. The proposed model is utilized to prioritize risks corresponding to the particular case study, based on real AV shuttle bus development, and focuses on the low-level hardware/software safety issues and improvements.

Contradictions of Online Motorcycle Taxi (Ojek) Arrangements as Public Motor Vehicles in Indonesia

There are various types of transportation services as facilities for community mobilization in Indonesia, one of them is an Ojek. Ojek as a two-wheeled transportation service considered as alternative public transportation which can transport a person from one place to another in a fast way and at affordable costs. With the development of technology and transportation in this digital era, conventional motorcycle taxi (in Indonesia: ojek konvensional) transformed into online motorcycle taxi (known as ojek online), a transportation service using an online application as the ordering media. However, currently, there is no regulation that regulates or legalizes the existence of the motorcycle taxi itself, until the emergence of online motorcycle taxi. With the issuance of Minister of Transportation Law Number 12 of 2019, which gave a perspective that motorbikes were legalized into public transportation, while the regulation in Indonesia Transportation Law stated that motorbikes were not public transportation and Constitutional Court Decision Number 41/PUU-XVI/2018 refuse the legality of motorbikes as the public transportation. The contradiction of the regulation of online motorcycle taxi has resulted an unclear legality of motorbikes used as an online transportation in Indonesia. Transportation Law as a higher regulation than Minister of Transportation Law does not regulate the classification of motorbikes as a public transportation which resulted a contradiction on the basis of the hierarchy of laws in Law Number 12 of 2011.

Skyport location problem for urban air mobility system

With rapid advancement in aerial vehicle technologies, air taxi is drawing keen interest as a new type of transportation service. One of the necessary elements for air taxi-based transportation service system is a skyport, which is a designated area for take-off and landing of air taxis. In planning a skyport network for air taxi transportation system, it is important to consider midair congestion between air taxis. Severe congestion increases the risk of collisions, which in turn increases the complexity in scheduling and routing in the subsequent operations phase.In this study, we propose a novel hub location problem (HLP) that incorporates traffic congestion caused by intersecting vehicles along hub-to-hub arcs. Modeling congestion in an HLP formulation involves nonconvex bilinear terms, which makes it difficult to solve. We tackle this challenge by exploiting a property of an optimal solution and reformulating the original model to obtain a linear formulation. We also develop a heuristic algorithm based on a genetic algorithm to handle large-size problems for practical applications. Using the proposed model and solution methods, extensive experiments have been conducted to study optimal design of air taxi network under various environments. Our analyses demonstrate that viability of air taxi service is a complicated function of many factors including collision risk, system cost, airspace design, to name a few. Our model can offer quantitative understanding of such complex relationships to assess and develop strategies to improve the viability of an air taxi transportation system.

Perancangan Aplikasi Pemesanan Travel Antar Kota Di Sumatera Barat Berbasis Android

The development in the field of technology is currently growing rapidly, one of the technological developments at this time is the internet. Then what is obtained by using the internet can also be utilized in the field of transportation, namely by making an Android mobile-based travel ticket booking information system using a smartphone. Travel is a type of transportation service that serves passengers with a door to door or pickup system at the booking address, then delivered to the destination address. However, the process of booking travel tickets today is still done traditionally by coming to the counter or branch office of travel so it takes a lot of time and is inefficient, and there are also several other ways to call a travel agent, sometimes such methods are not effective because of the occurrence of a pile of tickets without accurate data. Therefore this study aims to facilitate travel passengers in searching or booking Travel tickets in the West Sumatra Region by designing an Android mobile application. Apart from that in providing location information to the drivers of the traveling fleet to pick up passengers at certain locations by using Google Maps, and application features such as travel schedules, ticket checks, ticket reservations, and account registration.

Mobility-as-a Service jako postęp w integracji transportu

Mobility-as-a-Service (MaaS) is an innovative concept that makes a significant contribution to transport integration. This concept has developed following the emergence of new types of transport services and technological advances, in particular ICT and mobile technology. MaaS has the potential to improve the use of assets and contributes to a reduction in the number of passenger cars in congested cities. The aim of the article is to synthesise the current state of knowledge on the Mobility-as-a-Service concept, to assess the degree of the implementation of MaaS systems in Europe, to discuss the results of research on the benefits of using these solutions, as well as to show the role of MaaS in transport integration. The research methodology includes a literature review and a deductive research method. The research has shown that any consensus has been reached on the scope of the MaaS system, although the suggestion is that they should include solutions that have at least an integrated module for booking services and payments, in addition to the possibility of planning a journey by different transport means. Currently there are neither sufficient data on the costs and benefits of MaaS systems, nor comprehensive analyses how they affect travel patterns and user behaviour. However, the first fragmented studies of MaaS pilot implementations confirm the existence of benefits for different stakeholder groups. The analysis of levels and the scope of the integration in MaaS systems confirmed that they contribute to the deepening of the integration of transport services. The results of the research presented in this article can be a reason for in-depth research into the essence and effects of Mobility-as-a-Service applications.

Moment-based rental prediction for bicycle-sharing transportation systems using a hybrid genetic algorithm and machine learning

Bicycle-sharing systems are a new type of transportation service that provides bicycles for shared use; they allow users to rent a bicycle at one station, ride it, and return it to another station in the same city. A predictive model is needed to forecast the rental demand to improve user satisfaction and increase profits. To effectively predict the rental demand in such bicycle-sharing systems, we propose a moment-based model and a new hybrid approach that combines a fuzzy C-means (FCM)-based genetic algorithm (GA) with a back propagation network (BPN). This FCM-based GA is a new unsupervised classification method that is used to pre-classify historical rental records into groups. The classification results are then fed into a BPN predictor, which is trained using these categorized records. After training, the BPN predictor can predict the demand at future moments. Finally, we present a case study based on real-life data to demonstrate the effectiveness and efficiency of the proposed approach.

New Medium-Voltage DC Railway Electrification System

This paper highlights the potential of medium-voltage dc electrification for railway traction. A method is proposed for determining the dc voltage level in order to guarantee, in terms of traffic, equivalent performances to an ac-electrified railway line. Railroad traffic, type of transport service, and railway network topology being given, the analysis method takes into account the following constraints: voltage at the pantograph, heating of overhead line and rail-to-ground voltage. Once the dc voltage level is chosen, the dc electrification system is compared with a standard 25-kV ac electrification in the case of the French high-speed line from Paris to Strasbourg.

Совершенствование cистемы управления транспортно-экспедиционного обслуживания мебельных предприятий

The purpose of this study is forwarding services, since at present transport largely determines the opportunities for development of national economies. The basic requirements on the market are the terms of delivery of goods: at the right time, in the right place, with certain consumer characteristics, in the required quantities. All this highlights the issue of freight forwarding service and choice of optimal method of delivery. In recent years, the latest practices and technologies for the delivery of goods, based on the method of integration of transport and logistics, on the development of the latest technologies in the field of informatics and communications, have been introduced into the economic practice of transport and forwarding enterprises and firms. As in other industries, the market for forwarding services has become a market for buyers. Therefore, it is extremely important for transport and forwarding enterprises to study and analyze the needs of society in all types of transport services in order to meet them. Thus, the successful operation of such enterprises is impossible without the active application of marketing research in their business processes. The modern freight transport market is characterized by a greater variety of forms of service. However, the reforms carried out in the country have not been lifted, but, rather, deepened the contradictions of a socio-economic nature. As a consequence, the problems of regulating transport activities are growing and becoming more complicated, as determined by such factors as insufficient attention of the state and local authorities to the problems of transport; lack of holistic coordination mechanism for management, combining elements of overall system management and operational regulation of transport. In a rapidly changing world, it is necessary to quickly respond to the constantly emerging new demands and requirements. This is especially true in the sphere of services. Therefore, transport and forwarding enterprises in order to remain successful and competitive need to effectively organize their activities and offer quality services.

Lead time performance in a internet product delivery supply chain with automatic consolidation

Internet sales have increased exponentially in the last decade. Much of the internet sales are of physical products in urban areas that require product delivery transportation with a tight delivery lead time. With this challenge, a new type of transportation services has been developed aiming to cope with a strict control of transportation lead time. In this paper, an internet product delivery service with customer orders that are multi-item as well as single item is simulated. We address specifically the mismatch between supply and demand when retailers for any reason are unable to estimate the configuration of multi-item orders. Three scenarios of demand patterns are simulated (demand as forecasted, lower than forecasted and higher than forecasted) using discrete-event simulation to look at the effect on transportation lead time. Results show the positive effect on the mismatch between demand and resource capacity which is expressed in higher number delayed delivery orders. The excess of capacity in the product delivery supply chain has not a positive impact on delivery time of orders as technically orders are not delivered before the multi-item components are not available. This leads to think that the excess of resources are not an element that add value to customers waiting for their orders.

To Enhance Equity in Transportation Services by Providing Dial-a-ride System

This study is trying to give the top concern to the vulnerable people from transportation point of view. The very reason to initiate dial-a-ride system for the vulnerable group is to enhance the equity in transportation service. Dial-a-ride is a type of transportation service in paratransit system which consists of reservation, specialized vehicle delivery, professional care and other relative services for the vulnerable people. The vulnerable groups in Beijing are quite large but the existing public transit can’t come up with good services for them. Therefore this paper attempts to explore the build-up of dial-a-ride service system for disable people from the following five aspects: budget, system planning, training for operators, policy and publicity. It is our responsibility to make the vulnerable group enjoy the convenient services provided by civilized society. Apart from that the group can be treated equally in their choice of travel means. It is believed that dial-a-ride will become a part of our urban public transit systems and function as a demand-response system for fulfilling the travel desire of vulnerable group.

Exploration of Equity in Transportation Service by Providing Dial-a-Ride System for Vulnerable Group

This study is to explore the equal opportunity for vulnerable group to enjoy the same transportation services as general public do by provision of dial-a-ride system. Unlike the general definition the vulnerable group in this study is defined a group of people who can’t enjoy same right to access public transit service as general public do. The very reason to initiate dial-a-ride system for the vulnerable group is to address the needs to provide separate service for them and raise awareness of importance to build Dial-a-ride at local, regional and nationwide levels. The utmost importance of the study is to enhance the awareness of elected officials and transportation planners on the equity in transportation services. Dial-a-ride system has been developed maturely in some European countries and the USA. Dial-a-ride is a type of transportation service in paratransit system for ride-sharing purpose as well as for the disable group who can neither access to car nor public transit. This system mainly depends on the mini bus with neither a fixed line nor fixed time schedule. Dial-a-ride system itself can be more flexible so that it can meet special transportation demands as compared to general public transit. In general this system can be the complement of public transit. At the very beginning DAR system is used for the general groups. However DAR is also designed for providing transportation service for vulnerable groups such as aged and disable people. The system consists of reservation, specialized vehicle delivery, professional care and other relative services. With the development of civilized society, we should pay more attention to the vulnerable group when we try to allocate social resources equally. Vulnerable group is in this study defined a group of people who can’t enjoy same right to access public transit service as general public do. According to this, the purpose of establishing a dial-a-ride system for vulnerable groups is to make vulnerable groups enjoy the same transportation service as other commuters. The motivation behind conducting this study is to address the needs to provide transportation service system for vulnerable group and raise awareness of importance to build DART at local, regional and nationwide levels. Although the vulnerable groups in Beijing are quite large, dial-a-ride services have not been established, yet. From observation it is found that the existing public transit can’t come up with good services for the disable people. With regard to this situation the objective of this paper attempts to explore the build-up of dial-a-ride service for disable people from the following five aspects. First thing is budget. Dial-a-ride belongs to welfare type of thing for the public. Therefore, this system should enjoy receiving financial aid from all levels of governments as subsidy. Second thing is to work out system planning for dial-a-ride from transportation point of view. Regional as well as local centers should be set up to plan, design and manage dial-a-ride services for the city of Beijing because Beijing itself has more than 1 million disable people. The third thing is to conduct comprehensive training for operators. Since the service receivers are disable people it is necessary to provide technical and management training for the drivers and staff workers. The fourth thing is to set policy to make this system work. The last thing is the publicity of dial-a-ride service. Actually, publicity is the guarantee of the former four steps. It is our responsibility to make the vulnerable group enjoy the convenient services provided by civilized society. Apart from that the group can be treated equally in their choice of travel means. It is believed that dial-a-ride will become a part of our urban public transit systems and function as a demand-response system for fulfilling the travel desire of vulnerable group.

Adding flexibility in a natural gas transportation network using interruptible transportation services

Abstract We present a modeling framework for analyzing if the use of interruptible transportation services can improve capacity utilization in a natural gas transportation network. The network consists of two decision makers: the transmission system operator (TSO) and a shipper of natural gas. The TSO is responsible for the routing of gas in the network and allocates capacity to the shipper to ensure that the security of supply in the network is within given bounds. The TSO can offer two different types of transportation services: firm and interruptible. Only firm services have a security of supply measure, while the interruptible services can freely be interrupted whenever the available capacity in the transportation network is not sufficiently large. We apply our modeling framework on a case study with realistic data from the Norwegian Continental Shelf. The results indicate substantial increased throughput and profits with the introduction of interruptible services.

Transportation serviceability analysis for metropolitan commuting corridors based on modal choice modeling

Major commuting corridors in metropolitan areas generally comprise multiple transportation modes for commuters, such as transit (subways or buses), private vehicles, or park-and-ride combinations. During the morning peak hour, the commuters would choose one of the available transportation modes to travel through the corridors from rural/suburban living areas to urban working areas. This paper introduces a concept of transportation serviceability to evaluate a transportation mode’s service status in a specific link, route, road, or network during a certain period. The serviceability can be measured by the possibility that travelers choose a specific type of transportation service at a certain travel cost. The commuters’ modal-choice possibilities are calculated using a stochastic equilibrium model based on general travel cost. The modeling results illustrate how transportation serviceability is influenced by background traffic flow in a corridor, value of comfort for railway mode, and parking fee distribution.

A Simple Representation of a Complex Urban Transport System Based on the Analysis of Transport Demand: The Case of Region Ile-de-France

In densely urbanised areas the structure of the transport systems becomes quite complicated. Many types of transportservices are available and many types of modes are being used, thus offering a wide palette of transport options. How do all these transport services and modes relate to each other? In practice it proves to be quite hard to define such a structure. A number of classifications exist, based on transport modes, or on organisational characteristics. However, they often lack a theoretical underpinning, which makes them not always easy to apply in practice. This paper presents a new methodology that focuses on the traveller's perspective: how does the traveller use the many transport services and modes that are available? This method to determines the functional structure of a transport system on the basis of observed trips. This method is illustrated for the case of Region Ile-de-France, the urban area of Paris, using household travel survey data.The methodology consists of three steps. First, transport services and modes are grouped into “service modes”, which are homogenous from the perspective of travellers. Second, the zones served by each service mode are identified. Third, the relationships between the service modes are identified: Spatial complementarity; Hierarchical relationship (combining a fast mode with a scarce network and a slow mode serving a dense network); and Competition. As a result, we obtain a strategic representation of the structure of the urban transport system of Region Ile-de-France.

Welfare reform and the spatial divide: a study in transporting recipients to jobs

A number of studies supports the ineffectiveness of public transportation to connect low‐income individuals with entry‐level employment. The transportation obstacles faced by welfare recipients to find and maintain employment continue to persist. Focussing on the example of two programs implemented in suburban Washington, D.C., this study explores the question of what type of transportation services best support the welfare‐to‐work goals and whether they instill a sense of self‐reliance and esteem among participants. In addition, this study used the data to develop spatio — temporal travel pattern diagrams, which suggest that transportation may change the psychology of transit for recipients. The authors recommend that service providers give greater attention to outreach services and ensure better coordination between transit, childcare and job training programs. The paper also includes a number of suggestions to improve both skill and spatial mismatch.

Gender difference in the utilization and users' characteristics of community rehabilitation programs for cerebrovascular disease patients in Japan.

The purpose of this study was to see whether there was gender difference in the utilization of a community rehabilitation program for cerebrovascular disease (CVD) patients in Japan and to examine factors affecting this gender difference. For CVD patients who participated in 16 community rehabilitation programs in the Saitama prefecture (n = 190), we studied their clinical and functional status, socioeconomic conditions, the degree of family support, and their use of rehabilitation and transportation services. The general characteristics of the programs and the type of transportation services they offered were also surveyed. The female proportion of all the program participants was 34.2% and its proportion tended to be smaller when their ADL level was worse. However, such difference by gender lessened after the participants were stratified by the type of transportation services and by such conditions as being accompanied by a family member during transportation.

Razvoj i organizacija huckepack prijevoza u Europi

Piggy back technology of freight rail transport has particularly been invigorated .by the second world energy crisis of 1978. For purposes of relieving individual road routes, better utilization of rail infrastructure, reasons of environmental protection, lower costs, higher speed and safety of transport, the EEC supports financially the development of this aspect of transport technology. This paper deals with the existing organization/management of piggy-back transport in Europe with particular reference to the indices of efficiency of the German Society for Transport of Road Vehicles by Rail entitled 'Kombiverkehr A. G.'. Through identification of the forwarding agent as the organizer of shipment and delivery of goods by this technology the author refers us to the indispensability of this legal entity which as an entrepreneur acts on behalf of the business organization on completion of transport to satisfaction of the party providing and the party using this type of transport service.
