Legal Regime of the Settlement of Disputes Arising from a Contract of Multimodal Carriage of Goods within CEMAC Land lock Countries

CEMAC landlocked countries (specifically Chad and Central African Republic) depend solely on Cameroon who serves as a transit state for the transportation of goods to and from these landlocked countries. Thus, the entering into bilateral conventions helped to facilitate and create transit corridors for the transportation of goods amongst these countries. Meanwhile Cameroon which serves as a transit state to these landlocked countries has four modes of transport (road, rail, water and air), while Chad and Central African Republic have just two or three principal mode of transportation namely road, rail and air. However, these modes of transportation pose unique challenges, particularly in countries with limited infrastructure. Through doctrinal analysis of both primary and secondary sources of data, this article seeks to examine the legal framework in resolving disputes arising from contracts of multimodal carriage of goods available to landlocked countries of the Central African Economic and Monetary Community (CEMAC). Our findings revealed that, the legal framework in resolving disputes arising from contracts of multimodal carriage of goods available to landlocked countries are not effectively implemented. As a result, some salient recommendations have been made to bridge the gap between theory and practice amongst these countries in general and Cameroon in particular.

A Life Cycle Cost Comparison of Flexible Versus Rigidpavements in Nigeria: Case Study of Papalanto - Sagamu Road

The condition of roads in Nigeria, most of which are made from asphalt, is generally considered unsatisfactory. This has led to calls for a blanket switch from asphalt pavements to concrete pavements for new road construction. This study examines the characteristics and relative advantages of the two pavement types; and carried out the design and life cycle cost comparison of a case study road with heavy traffic and poor subgrade conditions. The results indicate that, the initial cost of construction is actually less for the concrete pavement by 12% when compared with the asphalt alternative, while the life cycle cost analysis further yielded an advantage of 36% for the concrete pavement. The paper therefore recommends that major roads, particularly those on the national and international transit corridor, being of heavy traffic, should be reconstructed as the need arises, as concrete pavements. The paper however further recommends that, axle load control should be enforced through the introduction of weigh bridges and that routine maintenance should mandatorily be carried out, as even the best constructed concrete pavements have failed due to lack of routine maintenance like clearing the road verges of weed and road sand and desilting of drainage structures

Enhancing Urban Resilience through Strategic Parking Pricing in Jakarta’s Bus Rapid Transit Corridors

Although Jakarta has invested in various mass transport systems, these efforts have not successfully reduced private vehicle use. Due to this, this study aims to analyze the impact of implementing TransJakarta bus rapid transit corridor-based high parking tariffs on travel mode choice, including road- and rail-based public transport, ride-hailing, taxi, car, and motorcycle. Involving 478 private vehicle users and implementing a nested logit model, some variables, including respondents’ income, travel time, egress time, parking costs, parking distance, travel cost, and parking surcharge, are considered to understand to what extent these variables influence the use of proposed travel mode in the future. The nested logit model shows that not all variables significantly influence travel mode use, specifically related to rail-based public transport choice among motorcyclists. Meanwhile,parking distance insignificantly influences the choice of all travel modes except cars among car users. The results also indicate that increasing parking tariffs insignificantly influences the likelihood of both motorcyclists and car users shifting to public transport. Motorcyclists and car users tend to continue using motorcycles but change parking locations with higher tariffs. Additionally, some shifts towards ride-hailing services and TransJakarta Bus Rapid Transit are found, meaning that there is potential for these alternatives to play a significant role in reducing private vehicle use. Based on the model results, additional push-based policies, such as the odd-even license plate rule, are necessary to effectively support the transition from private vehicle use to public transport. Implementing these policies is expected to significantly contribute to reducing traffic congestion and promoting a sustainable and resilient urban environment.

Control allocation optimization for an over-actuated tandem tiltwing eVTOL aircraft considering aerodynamic interactions

This paper describes control allocation strategies for a tandem tiltwing electric vertical take-off and landing (eVTOL) aircraft with distributed propulsion. The control mappings are constructed as local surrogate models that relate the control effectors to the aircraft's aeropropulsive forces and moments across the full flight envelope, including interactional aerodynamics effects. Control allocation optimization problems are formulated based on force and moment commands for specific flight conditions. Specifically, a nonlinear programming formulation based on nonlinear control mapping is proposed for control allocation optimization, and the problem is solved using a sparse nonlinear optimizer. The solutions obtained from different formulations such as the minimization of force and moment residuals and the minimization of control effort are investigated. Furthermore, these solutions are compared with the solutions obtained using linear control mapping-based formulations. Results presented for the cases of forward flight, low speed flight & hover, and flight in the transition corridor suggest that considering aerodynamic interactions while formulating and solving the control allocation problem is necessary for higher levels of accuracy compared to linear approaches. One-propeller-out scenarios and moment and force generation cases are also investigated. Finally, control allocation for steady and accelerated operation in the transition corridor is discussed. The contribution of the methods and results in the paper is a nonlinear control allocation methodology for the entire flight envelope of an over-actuated tandem tiltwing eVTOL aircraft.

Association of transit-oriented development with transit use: Effects of gentrification and spatial autocorrelation

The empirical evidence in the existing literature primarily supports the positive association of transit-oriented development (TOD) with transit use. However, indirect relationships between TOD and transit use may be observed due to TOD-induced gentrification and spatial autocorrelation. This research examined the relationships between TOD, gentrification, and transit use with the consideration of spatial autocorrelation. The study observations were from the gentrifiable neighborhoods in Taipei City, Taiwan, and were analyzed using simultaneous equation models and spatial regression methods. Empirical results reveal three major findings: 1) A positive and direct association of TOD-ness with the modal share of transit substantially occurs and confirms the findings in the existing literature. 2) A negative and indirect association of TOD with transit use mediated by gentrification may occur under the moderation of rising car ownership. 3) A positive spatial autocorrelation of transit use substantially occurs between adjacent neighborhoods. These findings prompt local administrations to implement TOD policies containing or being accompanied by instruments inhibiting car ownership throughout urban areas rather than just along major transit corridors.

Railway bridge “Under Vyšehrad” in Prague, preparation of reconstruction

AbstractThe railway bridge in Prague under Vyšehrad is a steel riveted structure with a lower deck from 1901 connecting the right and left banks of the Vltava River. The bridge is double‐track and is located on a national track included in the TEN‐T system. This is the transit corridor Nuremberg – Pilsen – Prague – Brno – (Vienna, Bratislava, Poland). It is therefore one of the busiest railway bridges in the Czech Republic. The bridge is a cultural monument.At the moment, it is also the best‐known and most discussed railway bridge in the Czech Republic. The bridge has been in service for more than 120 years and its expected lifespan has long been exceeded. The railway needs to increase the track capacity. At the same time, it is being discussed what to do with the heritage‐protected bridge. Repair? Replace? Shift? These are the questions and challenges facing the Railway Administration.

The World s Leading Transport and Transit Hub: Azerbaijan-Türkiye-Georgia

In the new world order established after the collapse of the USSR at the end of the 20th century, mutual and beneficial cooperation between states located in close geographical proximity came to the fore. In this regard, the South Caucasus, as one of the most sensitive geopolitical regions of the world with rich resources, stands out. New formats of cooperation began to emerge in the Caucasus. Principally, high-level strategic relations have been established between Türkiye, Azerbaijan and Georgia. Cooperation between the countries was expanded for the most part in the field of transport. Obviously, the creation of the Azerbaijan-Georgia-Türkiye triangle was caused by historical and cultural ties, geographic neighborhood, being part of a single transit corridor, favorable conditions and political will. The territory of Georgia was especially stand in need of the general infrastructure transport projects implementation in the region. Due to the fact that Georgia is a transit country, that ensures the transition between Europe and Asia. Furthermore, the aggressive policy of Armenia, another South Caucasus country, made Georgia a country of convenience. All the same, the establishment of a railway connection between the three countries has formed a favorable ground for Central Asian republics, which have great transport potential, to Türkiye and other European countries. Currently, cooperation relations between the three states in both bilateral and multilateral formats are to be remained unaltered. In terms of transport and transit issues, the region will gain a more significant position with the implementation of projects between Türkiye , Georgia, and Azerbaijan.

Time Optimal Altitude-Hold Flight Mode Transition Strategy for a Class of Ducted Fan Tail Sitter UAV

For special tail sitter configurations such as the ducted fan tail sitter unmanned aerial vehicle (UAV), the widely used trajectory planning methodology based on differential flatness might not be applicable due to complex aerodynamic coupling effects. As a result, the flight mode transition remains a challenging task. In this paper, we address the time optimal altitude-hold flight mode transition issue for a class of ducted fan tail sitter UAV. The foundation of the framework is the dynamic transition corridor in which the limitation of jerk is particularly considered, aiming to thoroughly reflect the dynamic feature of aggressive maneuvers. Based on this, we propose a time optimal strategy to generate feasible altitude-hold transition trajectories. Simultaneous, by fully utilizing the manifestation of time optimal altitude-hold flight behavior revealed by the transition corridor, we try to tackle the time optimal altitude-hold transition by means of a novel model-free control scheme. Comparative simulations show that both of the transition strategies achieve satisfactory performance on time optimal altitude-hold transition in the absence of disturbance, while the model-free control scheme exhibits better robustness under external disturbance.

Managing oversaturation in BRT corridors: A new approach of timetabling for resilience enhancement using a tailored integer L-shaped algorithm

Bus rapid transit (BRT) is a high-capacity public transport system that typically operates along urban transit corridors with dense travel demand. Maintaining the efficiency and stability of the BRT is paramount for daily transport operations. Owing to the difficulty in ensuring an exclusive right-of-way along the entire route, stochastic congestion events may occur resulting from road segments without dedicated BRT lanes. This may lead to volatility in travel time and resulting in passenger stranding, determined as common-case disruptions in this study. These common-case disruptions frequently occur in the daily operation of oversaturated BRT routes. To manage and mitigate their negative impacts, a novel timetabling problem for enhancing the resilience of a BRT system was proposed to assess the ability of the system to withstand and recover from these disruptions. We formulated the problem as a two-stage stochastic mixed-integer optimization model and designed an exact algorithm based on a tailored integer L-shaped method. We then analyzed the structural properties of our model and developed several acceleration techniques to further improve the efficiency of the algorithm. The computational results show that the proposed algorithm outperforms the commercial solver in large-scale instances and can provide near-optimal solutions when the commercial solver is invalid. Besides, external comparisons with dynamic programming also demonstrate the superiority of the proposed algorithm in solution efficiency. Compared with the benchmark timetabling problem, which aims to reduce passenger waiting time, the proposed method can efficiently reduce the duration of the oversaturation period by 35.3%.

The Chabahar Transit Project: Transition from Geo-Politics to Geo-Economics

ABSTRACT The Chabahar Transit Project is a multimodal network linking India, Iran, Afghanistan, and, recently, Uzbekistan, through maritime, rail, and road routes. The project results from a complex combination of interests and goals of the member countries and is a clear example of the transition from geo-politics to geo-economics. Iran looks at the Chabahar part as the only ocean port of the cautery and golden gate to landlocked Afghanistan and Central Asia to increase Iran’s capacity in the International North-South Transport Corridor (INSTC). India looks at the Chabahar transit project as a part of the “Diamond Necklace Strategy” against China’s “String of Pearls” Strategy and also bypassing the traditional rival, Pakistan, especially to counter China’s massive investment in the development of Pakistan’s Gwadar port, as well as the China-Pakistan Economic Corridor (CPEC). Finally, the Russo-Ukraine war and the block of east-west transit corridors traversing Russian territory into Europe have increased the role of the Chabahar transit project in the INSTC. However, the possible failure of negotiations to revive the JCPOA and the re-imposition of UN Chapter 7 sanctions against Iran is the most crucial challenge for the Chabahar transit project and the India-Iran-Afghanistan-Uzbekistan quadrilateral agreement.

Longitudinal dynamic envelope solution and transition path optimization based on reachability analysis for fixed-wing VTOL UAVs

Flight velocity and tilt angle are commonly employed to define the safe region for fixed-wing vertical take-off and landing (FW-VTOL) UAVs as they undergo tilting, referred to as the transition corridor. Nevertheless, the transition corridor only considers the aircraft's limitations in a quasi-stationary condition and ignores the additional constraints introduced by the aircraft's kinematic behavior. To obtain a more accurate safe state space, the concept of the dynamic envelope was proposed by previous researchers. The dynamic envelope of UAV represents the safe state space taking into account aerodynamic constraints and kinematic constraints. Solving the dynamic envelope has consistently remained a focal point of research in the field. This study introduces an innovative approach that employs reachability analysis to solve the dynamic envelope of the FW-VTOL UAV during the transition stage. Building upon this, it proposes a safety index for the transition path, optimized to determine the safest transition path. Subsequently, specific case studies verified the effectiveness of the solution process and optimization method. The designed optimal path enhances safety by 9.71% compared to the basic path, signifying its practical significance in mitigating risk during the transition stage of FW-VTOL UAVs. Furthermore, the attributes of the transition path are analyzed based on two aspects: (A) a comparison between the optimal transition path and the two-dimensional transition path with a constant angle of attack; (B) an examination of how key UAV design parameters influence the transition path's safety. Overall, the methodology and general rules proposed in this study provide a theoretical basis and technical support for improving the security of FW-VTOL UAVs in the transition stage.

Since independence, Georgia’s full-fledged integration into the European Union is not only the foreign policy goal of our country, but also the driving force for the construction and development of a democratic state. Georgia’s strategic location and possession of rich renewable, unconventional energy resources give us a unique chance to become a hub, a “middle corridor” and a conduit for “green energies”. Georgians are ready to use this opportunity for further alignment with the ambitious energy goals of the European Union and the “Green Agreement” of Europe. Our push towards the European Union has been preceded by intensive communication and cooperation on energy legislation, regulations and energy policy, as well as improving energy infrastructure. This is how the so-called mega-project of the 21st century – the Black Sea submarine cable project – was created. The initiative involved in the project is more than simple infrastructure development; It is a symbol of Georgia’s integration and interconnection with the European Union. The Black Sea submarine cable will not only enhance energy security and diversity, but also serve as a renewable energy exchange channel between Asia and Europe. The idea of the Black Sea submarine cable project was born in Georgia, and Georgian geologists carried out technical works to explore the bottom of the Black Sea. At the next stage, Azerbaijan, Romania and Hungary were included in this project. The most important agreement was signed by the representatives of all four countries. The purpose of our research is to determine in advance what economic benefits Georgia will receive during the implementation of this important project, and we will be able to export the energy of renewable resources of our country, if we remain only as a transit corridor, which is also very attractive, although less profitable. While working on the article, we evaluated the potential of Georgia’s renewable, non-traditional energy sources, their target indicators and characteristics. Based on the researched information, we developed conclusions and recommendations. Keywords: renewable, non-conventional energy resources, Black Sea submarine cable, energy security, “green energy”, European integration. VIEW ARTICLE

Research on transition corridor of distributed tilting power configuration

For a distributed tilt-power configuration aircraft, the transition corridor was studied based on limited conditions such as wing lift characteristics and propeller power requirement. By establishing the dynamic model of each component and balancing according to the balance equation, the boundary of the transition corridor of distributed tilting dynamic configuration is determined. The results show that the minimum forward flight speed required for a low Angle of attack is less than that for a high Angle of attack; the wing lift characteristic high-speed boundary and the propeller power limit boundary together form the high-speed boundary of the transition corridor.

The result of the study analysis shows that the development of the Greater Bandung Area can be done by prioritizing 7 (seven) main points of interest which are translated into 9 (nine) nodes. These nodes can be connected into 2 (two) main corridors as the backbone and 21 feeder corridors.

How Iran Perceives Turkey’s Rise in the South Caucasus

As the geopolitical landscape of the South Caucasus continues to evolve, multiple divergent interests are bringing new dynamics into the Iran-Turkey relations. The article explores Iran’s changing perceptions concerning the South Caucasus in general and Turkey’s assertive geopolitical activism in the region, in particular. The authors argue that, given Turkey’s increasing influence in the South Caucasus and Iran’s decreasing footprint in the region, the current geopolitical and geo-economic trends are likely to bring more conflict into the Iran-Turkey regional rivalry. Tehran is apprehensive of several key insecurities stemming from Ankara’s growing activism in the South Caucasus. Apart from historical disagreements between Iran and Turkey over the Armenia-Azerbaijan conflict, the East-West transit corridors and pan-Turkism in a bigger picture, Tehran perceives the underlying developments in the region as part of the West’s “geopolitical plot” of containing Iran, in which Turkey plays a strategic role. Consequently, the South Caucasus is increasingly becoming an additional source of regional confrontation between Iran and Turkey.

Impact of “light” bus rapid transit (BRT-light) on traffic and emissions in a travel corridor

Our study compared observed traffic volumes in the Bus Rapid Transit (BRT-Light) corridor to those predicted using two different quasi-experimental methods. The first quasi-experimental design, referred to as interrupted time series, assumes the trends in traffic on BRT alignment from 2013 to 2017 continue through to 2019 after BRT-Light is in place. Making that assumption, traffic volume on the BRT alignment is 2514 vehicles per day lower (−7.38%) than one would expect based on the preexisting trend. The second quasi-experimental design is called a before-after design with a control group, which assumes that traffic volume on the BRT route would increase by the same percentage as traffic on parallel streets to the BRT line, that is 2.30 percent or 645 VPD between before and after. Also, BRT alignment's traffic volume was reduced by 1249 VPD or 4.78 percent more rather than outside of BRT corridor, and 17,632 VPD or 9.33 percent considering trip generation. Meanwhile, transit ridership in the corridor increased by 8687 passengers per day (122.66%) more than expected with the introduction of BRT, which helps account for the effective reduction of vehicular traffic on the streets that comprise the BRT alignment. Through the section analysis, we found that dedicated right-of-way reduced traffic effectively. Our estimates suggest that BRT-Light will result in an annual reduction of 17,886,229 pounds of CO2 emissions and 914,614 gallons of gasoline consumption. Based on these results, we conclude that BRT-Light had a positive effect on easing vehicle traffic volume and emissions in the Provo-Orem metropolitan area.
