“…To the best of our knowledge, there are no specific regulations in terms of 24.5-foot containers, which are a bit unusual for the shipping industry. Hence, we refer to the regulations summarized in Grislis (2010) for 20-foot containers, which are the most similar to the 24.5-foot containers of this case study. According to this paper, an LCV can carry up to six 20-foot containers, but this is not a close scenario for this case study.…”

“…In addition, recent advances in mechanical technologies give rise to the use of the so-called Longer Combination Vehicles (LCVs), which can carry more than two 24.5-foot containers per truck (Grislis, 2010). Since they are proven to be effective from the technological point of view, the EU has set up regulations for permitting their use according to the so-called Modular Concept Vehicles (European Council, 2014): the maximum length is 25.25 m and the maximum weight is 60.0 t, whereas larger lengths and weights are allowed out of Europe (Nagl, 2007).…”

This paper presents the case study of an Italian carrier, Grendi Trasporti Marittimi, which provides freight transportation services by trucks and containers. Its trucks deliver container loads from a port to import customers and collect container loads from export customers to the same port. In this case study, all import customers in a route must be serviced before all export customers, each customer can be visited more than once and containers are never unloaded or reloaded from the truck chassis along any route. We model the problem using an Integer Linear Programming formulation and propose an Adaptive Guidance metaheuristic. Our extensive computational experiments show that the adaptive guidance algorithm is capable of determining good-quality solutions in many instances of practical or potential interest for the carrier within 10 min of computing time, whereas the mathematical formulation often fails to provide the first feasible solution within 3 h of computing time

“…Obviously, this problem would not occur if LHVs traveled on highways allowing only one-way traffic. Grislis (2010) evaluated the effect in road safety of longer combination vehicles (LCVs). He was not able to find empirical evidence that these vehicles, particularly shorter LCVs of 25.25 meters, are significantly more dangerous than standard heavy vehicles.…”

Are Longer and Heavier Vehicles (LHVs) Beneficial for Society? A Cost Benefit Analysis to Evaluate their Potential Implementation in Spain

et al. 2014

In this paper we carry out a thorough review of the current research related to the benefits and costs arising from the implementation of longer and heavier vehicles (LHVs). From this review we concluded that despite the many studies available, little has been said about the sensitivity of the benefits and costs to the ultimate performance of the key variables related to the evolution of the economy, road transport performance, safety, and so on. In order to fill this gap, we have designed a sensitivity approach based on a cost benefit analysis tool to determine which variables demonstrate the greatest influence on the benefits and costs stemming from the implementation of LHVs. In order to test the methodology, we have used it in an analysis of the Spanish trunk network. The results show that the benefits of LHVs for society are significant. Even in the least favorable scenario, the economic benefits are greater than E3500 million over 15 years, and the environment enhanced as well, for CO 2 emissions are reduced by 2 Million tonnes. Overall we noted how the results are not very sensitive to the evolution of key variables in determining the final outcome. However, we found that the variables that have the greatest affect on the final benefit, such as traffic growth and social discount rate, depend basically on the performance of the overall economy. Moreover, the private cost for haulers seems to be more important in determining the final benefit than externality costs.

“…Research on developing automated vehicles to improve the safety and efficiency of highways or freeways is indeed one of the most extensively studied topics in the field of intelligent transportation systems (ITS) that can be divided into two areas one of which is centred on roadway infrastructure, and its primary aim is to add information and communications technology to make driving easier (Junevicius, Bogdevicius 2009;Cah §kanelli et al 2009;Boumediene et al 2009). The other is centred on vehicles, and its goal is to develop driving assistance that reduces dependence on the driver (Prentkovskis et al 2010a(Prentkovskis et al , 2010bSkrickij, Bogdevicius 2010;Grislis 2010;Sapragonas, Darguzis 2011). The present work falls into the second category, specifically on reducing the likelihood of collision by means of an emergency braking system based on vehicle to vehicle communications (V2V).…”

Making Transport Safer: V2v-Based Automated Emergency Braking System

et al. 2011

An important goal in the field of intelligent transportation systems (ITS) is to provide driving aids aimed at preventing accidents and reducing the number of traffic victims. The commonest traffic accidents in urban areas are due to sudden braking that demands a very fast response on the part of drivers. Attempts to solve this problem have motivated many ITS advances including the detection of the intention of surrounding cars using lasers, radars or cameras. However, this might not be enough to increase safety when there is a danger of collision. Vehicle to vehicle communications are needed to ensure that the other intentions of cars are also available. The article describes the development of a controller to perform an emergency stop via an electro-hydraulic braking system employed on dry asphalt. An original V2V communication scheme based on WiFi cards has been used for broadcasting positioning information to other vehicles. The reliability of the scheme has been theoretically analyzed to estimate its performance when the number of vehicles involved is much higher. This controller has been incorporated into the AUTOPIA program control for automatic cars. The system has been implemented in Citroën C3 Pluriel, and various tests were performed to evaluate its operation.
