Problem definition: “Slugging,” or casual carpooling, refers to the commuting practice of drivers picking up passengers at designated locations and offering them a free ride in order to qualify for high-occupancy vehicle (HOV) lanes. Academic/practical relevance: It is estimated that tens of thousands of daily commuters rely on slugging to go to work in major U.S. cities. As drivers save commute time and passengers ride for free, slugging can be a promising Smart Mobility solution. However, little is known about the welfare, policy, and environmental implications of slugging. Methodology: We develop a stylized model that captures the essence of slugging. We characterize commuters’ equilibrium behavior in the model. Results: We find that slugging indeed makes commuters better off. However, the widely observed free-ride tradition is socially suboptimal. As compared with the social optimum, commuters always underslug in the free-slugging equilibrium when highway travel time is insensitive to slugging activities but may overslug otherwise. The socially optimal outcome can be achieved by allowing pecuniary exchanges between drivers and passengers. Interestingly, passengers may be better off if they pay for a ride than if they do not under free slugging. We also find that although policy initiatives to expand highway capacity or improve public transportation always increase social welfare in the absence of slugging, they may reduce social welfare in areas where free slugging is a major commuting choice. Nevertheless, these unintended consequences would be mitigated by the introduction of pecuniary exchanges. Finally, contrary to conventional wisdom, slugging as a form of carpooling can result in more cars on the road and thus, more carbon emissions. Managerial implications: Our results call upon the slugging community to rethink the free-ride practice. We also caution that slugging benefits commuters possibly to the detriment of the environment.

Transit stations are generally well known as nodes of spaces where percentage of people walking are relatively high. The issue is do more planning is actually given to create walkability. Creating walking led transit stations involves planning of walking distance, providing facilities like pathways, toilets, seating and lighting. On the other hand, creating walking led transit station for women uncover a new epitome. Walking becomes one of the most important forms of mobility for women in developing countries nowadays. Encouraging women to use public transportation is not just about another effort to promote the use of public transportation but also another great endeavour to reduce numbers of traffic on the road. This also means, creating an effort to control accidents rate, reducing carbon emission, improving health and eventually, developing the quality of life. Hence, in this paper, we sought first to find out the factors that motivate women to walk at transit stations in Malaysia. A questionnaire survey with 562 female user of Light Railway Transit (LRT) was conducted at LRT stations along Kelana Jaya Line. Both built and non-built environment characteristics, particularly distance, safety and facilities were found as factors that are consistently associated with women walkability. With these findings, the paper highlights the criteria  which are needed to create and make betterment of transit stations not just for women but also for walkability in general.

Problem definition: The eco-toxicity arising from unused pharmaceuticals has regulators advocating the benign design concept of “green pharmacy,” but high research and development expenses can be prohibitive. We therefore examine the impacts of two regulatory mechanisms, patent extension and take-back regulation, on inducing drug manufacturers to go green. Academic/practical relevance: One incentive suggested by the European Environmental Agency is a patent extension for a company that redesigns its already patented pharmaceutical to be more environmentally friendly. This incentive can encourage both the development of degradable drugs and the disclosure of technical information. Yet, it is unclear how effective the extension would be in inducing green pharmacy and in maximizing social welfare. Methodology: We develop a game-theoretic model in which an innovative company collects monopoly profits for a patented pharmaceutical but faces competition from a generic rival after the patent expires. A social-welfare-maximizing regulator is the Stackelberg leader. The regulator leads by offering a patent extension to the innovative company while also imposing take-back regulation on the pharmaceutical industry. Then the two-profit maximizing companies respond by setting drug prices and choosing whether to invest in green pharmacy. Results: The regulator’s optimal patent extension offer can induce green pharmacy but only if the offer exceeds a threshold length that depends on the degree of product differentiation present in the pharmaceutical industry. The regulator’s correspondingly optimal take-back regulation generally prescribes a required collection rate that decreases as its optimal patent extension offer increases, and vice versa. Managerial implications: By isolating green pharmacy as a potential target to address pharmaceutical eco-toxicity at its source, the regulatory policy that we consider, which combines the incentive inherent in earning a patent extension on the one hand with the penalty inherent in complying with take-back regulation on the other hand, serves as a useful starting point for policymakers to optimally balance economic welfare considerations with environmental stewardship considerations.

Problem definition: We study the disproportionate impact of the lockdown as a result of the COVID-19 outbreak on female and male academic research productivity in social science. Academic/practical relevance: The lockdown has caused substantial disruptions to academic activities, requiring people to work from home. How this disruption affects productivity and the related gender equity is an important operations and societal question. Methodology: We collect data from the largest open-access preprint repository for social science on 41,858 research preprints in 18 disciplines produced by 76,832 authors across 25 countries over a span of two years. We use a difference-in-differences approach leveraging the exogenous pandemic shock. Results: Our results indicate that, in the 10 weeks after the lockdown in the United States, although total research productivity increased by 35%, female academics’ productivity dropped by 13.2% relative to that of male academics. We also show that this intensified productivity gap is more pronounced for assistant professors and for academics in top-ranked universities and is found in six other countries. Managerial implications: Our work points out the fairness issue in productivity caused by the lockdown, a finding that universities will find helpful when evaluating faculty productivity. It also helps organizations realize the potential unintended consequences that can arise from telecommuting.

Increasing the number of vehicles in Special Region of Yogyakarta caused by congestion occurred at various traffic points in Special Region of Yogyakarta. The solution to reducing congestion is by increasing the use of public transportation within the city, but it still not in demand by the public. Optimizing daily activities, community always tries to avoid the traffic density on the road to be bypassed.Some research on social media has been used to detect traffic density anomalies. However, the system still cannot provide traffic density information on roads that will be passed by the user because it is just a mapping. Based on this problem, this study aims to classify the traffic density on the road that will be passed by users in the Special Region of Yogyakarta into the category of high traffic and low traffic by utilizing Twitter and GPS data.The results show that Android Applications are able to classify traffic density on the road to be traversed using Geonames.org API. Using the naïve bayes classification algorithm, the system can classify traffic density on 14 streets with an average accuracy of 77.5%, 90% precision, 79.1% recall, and 82.8% f-score.

As the population in Egypt is ever expanding, it is reflected in the increase of the number of vehicles on the road. Public transportation is the solution and the number of available buses can cover a significant amount of the population demand. However, the outdated state of the transportation infrastructure, the static nature of the lines and indistinct schedules create a confounding and unappealing user experience which prompts the users to stray to cars for their needs. So, an Intelligent Urban Transportation System (IUTS) is a must. IUTS is a multi-layered system which provides the solution for most of these problems. It operates on different layers starting from a real time vehicle tracking for transparent and efficient management of assets, cash-less ticketing done through RFID cards, vehicle health and diagnostic data for creation of automated maintenance schedules and a friendly interactive driver interface. In this paper an approach based on combining all these technologies is discussed where the hardware component is implemented based on System-on-Chip technology with custom hardware to interface with the vehicle. The data collected from the on-board unit is sent to the cloud, and with the help of machine learning algorithms the dynamic responsiveness of the system is guaranteed. The proposed system outperforms other existing ones through the dynamic and optimized routing feature for the bus navigation to optimize the operating cost but still satisfy the passengers’demand.

Increasingly diverse community mobility now results in an increase in the need for transportation equipment, both in terms of quantity and quality, however, on the other hand the available public transportation facilities are far from what is expected. This encourages to be encouraged to have a private facility. Today the development of motorized vehicle use is increasing rapidly. This is because motorized vehicles have advantages compared to public transportation, for example in terms of comfort and safety when on the road. The increase in transportation needs also boosted the growth of Consumer Financing Institutions perceived by consumers as a simpler procedure compared to bank financing institutions. The agreement signed between consumers and the Consumer Financing Institution is a standard agreement, in which consumers have no right to determine the contents of the agreement. This leads to the frequent occurrence of defaults on the part of consumers, because consumers do not understand the contents of the agreement properly. Good faith is an agreement principle that can control the occurrence of agreements that tend to incriminate parties. This paper aims to reveal the role of the principle of good faith in the establishment and implementation of the Consumer Financing Agreement. The study method used is a normative and philosophical study method based on secondary data.

Pelayanan publik merupakan elemen yang sangat penting dalam penyelenggaraan pemerintahan. Inovasi yang dibuat oleh Pemkot Surabaya bersama Dishub Kota Surabaya berkaitan dengan sistem parkir online yang disebut Park and Ride TIJ. Inovasi pelayanan ini diciptakan untuk mengatasi permasalahan peningkatan kepemilikan kendaraan di Kota Surabaya yang membuat kebutuhan parkir meningkat, tetapi tidak diikuti dengan penambahan lahan parkir. Parkir di badan jalan mengakibatkan pergerakan lalu lintas terhambat sehingga terjadi kemacetan terutama di pusat keramaian tengah kota seperti Jalan Wonokromo, Jalan Darmo, dan Jalan Setail. Tujuan penelitian ini ialah untuk mendeskripsikan Inovasi Pelayanan Publik Park and Ride TIJ Oleh Dishub Kota Surabaya. Jenis penelitian yang digunakan adalah deskriptif dengan pendekatan kualitatif. Fokus penelitian dengan teori milik Yogi Suwarno (2008:19) yaitu aspek-aspek penting yang menunjukkan suatu organisasi telah melakukan inovasi meliputi Pengetahuan Baru, Cara Baru, Objek Baru, Teknologi Baru, dan Penemuan Baru. Teknik pengumpulan data melalui wawancara, observasi, dan dokumentasi. Teknik analisis data menggunakan reduksi data, penyajian data dan ditarik kesimpulan berdasarkan data yang menjawab rumusan masalah. Hasil dari penelitian ini adalah semua fasilitas yang ada di Park and Ride TIJ sudah sangat bagus dan memenuhi kebutuhan masyarakat. Hanya saja kurangnya kesadaran masyarakat untuk menggunakan fasilitas yang sudah disediakan oleh pemerintah. Setelah didirikan Park and ride pun masih ditemukan masalah yakni banyak masyarakat masih melakukan parkir liar terutama pengunjung Kebun Binatang Surabaya, serta sopir angkot yang “ngetem” di pinggir jalan sehingga menimbulkan kemacetan. Kemudian terkait dengan penerapan e-payment, karena banyak masyarakat masih menggunakan uang tunai untuk pembayaran parkir di Park nad Ride TIJ. Kata Kunci: Pelayanan Publik, Inovasi Pelayanan, Park and Ride   Public service is a very important element in government administration. The innovation made by the Surabaya City Government and the Surabaya City Transportation Agency is related to an online parking system called the TIJ Park and Ride. This service innovation was created to solve the problem of increasing vehicle ownership in the city of Surabaya which makes parking needs increase, but not followed by additional parking lots. Parking on the road causes traffic movement to be hampered, resulting in congestion, especially in the downtown area such as Jalan Wonokromo, Jalan Darmo, and Jalan Setail. The purpose of this study was to describe the TIJ Park and Ride Public Service Innovation by the Surabaya City Transportation Agency. This type of research is descriptive with a qualitative approach. The focus of research with Yogi Suwarno's (2008: 19) theory is important aspects that show an organization has made innovations including New Knowledge, New Methods, New Objects, New Technologies, and New Inventions. Data collection techniques through interviews, observation and documentation. Data analysis techniques used data reduction, data presentation and conclusions drawn based on data that answered the problem formulation. The result of this research is that all existing facilities at the TIJ Park and Ride are very good and meet the needs of the community. It's just a lack of public awareness to use the facilities provided by the government. After the establishment of Park and Ride, problems were still found, namely that many people were still parking illegal, especially visitors to the Surabaya Zoo, as well as public transportation drivers who "stuck" on the side of the road, causing congestion. Then related to the application of e-payments, because many people still use cash for parking payments at TIJ Park nad Ride. Keywords: Public Service, Service Innovation, Park and Ride

Road users other than online public transportation must also be given legal protection and together enjoy the convenience of traffic facilities. Drivers are required to concentrate while driving a vehicle. This is regulated in Law Number 22 of 2009 concerning Road Transportation Traffic, Article 106 that everyone driving a motorized vehicle on the road is obliged to drive his vehicle fairly and with full concentration. The observations made were that attaching a communication device to online public transportation proved that the telephone was used while driving a vehicle. Communicating by telephone while driving a vehicle will cause an accident that will harm other road users. This study discusses the regulations for using the telephone while driving against online motorcycle taxis and law enforcement analysis the regulations for using the telephone while driving against online motorcycle taxis in Bandar Lampung. The results showed the telephone regulations while driving to online motorcycle taxis in Bandar Lampung were Permenhub No. 12 of 2019 Article 4, Article 6, Article 17, Article 18, and Article 19. The results of the analysis of law enforcement on the use of telephones while driving in the form of online motorcycle taxis to contact consumers on their way to the location 3 (three) times, namely 32% (thirty-two per cent) and the intensity of online motorcycle taxis to contact consumers more than 3 (three) times, namely 27% (twenty-seven percent). The analysis data has proven that the intensity of contacting passengers is very much done while driving. Online motorcycle taxi drivers do not obey the rules because they communicate more by telephone while driving.

Problem definition: We consider the problem faced by a welfare-maximizing service provider who must make a decision on how to split a fixed quantity of resources between two variants of the service: a standard variant and an expedited variant. The service is mandatory, but customers can choose between the two variants. Choosing the expedited variant requires enrollment that incurs a fixed cost per period. Customers are strategic and have the same cost of waiting but are heterogeneous in the rate at which they use the service. Academic/practical relevance: The option of expedited security at U.S. airports (TSA PreCheck) is an instance where this problem arises. As has been the case with the PreCheck program, providers that offer expedited service may face criticism from customers, with the main concern being that the diversion of resources to expedited services increases wait time for regular customers. This has important policy implications for the provider, especially a government organization such as the TSA. Existing literature has focused on service differentiation as a means to maximize profit or overall social welfare, but its effect on individual customers has received little attention. Methodology: We find customer’s equilibrium decisions for any allocation choice made by the provider. Using the equilibrium result, we solve for the allocation choice that maximizes social welfare. Results: Even when customers behave strategically, an expedited service offered in parallel to a standard service cannot only increase overall welfare, but also do so for each customer individually. We also find that in a scenario where some customers lose out because of the expedited service, improving the efficiency of the expedited service is more effective than decreasing the enrollment cost to help those who are worse off. Managerial implications: The gains from offering expedited service do not have to come at the expense of regular customers. When they do, we provide recommendations for which decision levers are most effective at making the system fair.

The Impact

Problem definition: Autonomous vehicles (AVs) are predicted to enter the consumer market in less than a decade. There is currently no consensus on whether their presence will have a positive impact on users and society. The skeptics of automation foresee increased congestion, whereas the advocates envision smoother traffic with shorter travel times. We study the automation controversy and advise policymakers on how and when to promote AVs. Academic/practical relevance: The AV technology is advancing rapidly and there is a need to study its impact on social welfare and the likelihood of its adoption by the public. Methodology: We use supply-demand theory to find the equilibrium number of trips for autonomous and regular households. We develop a simulation model of peer-to-peer AV sharing. We compare the socially optimal level of automation with the selfish adoption patterns where households independently choose their vehicle type. Results: We establish that the optimal social welfare is influenced by: (i) the network connectivity, that is, the ability of the infrastructure to serve AVs, (ii) the additional comfort provided by AVs that allows passengers to engage in other productive activities instead of driving, and (iii) the AV sharing patterns that reduce ownership costs, but create empty vehicle trips that increase congestion. Managerial implications: We investigate the impact of AVs in a case study of Toronto and show that partial automation maximizes social welfare. We show that the comfort of AVs may add traffic that compromises social welfare. Moreover, although traffic increases with automation, travel times may decrease because of significant improvements in traffic flow caused by AV connectivity in the network.
