The Impact

The Case Study section of the International Journal of Entrepreneurship and Innovation serves two purposes. First, the case studies presented are concerned with problematical issues that are pertinent to students of entrepreneurship. Thus they constitute appropriate teaching and learning vehicles on a variety of postgraduate and undergraduate programmes. Each case study is accompanied by a set of guidelines for the use of tutors. Second, it is envisaged that those engaged in entrepreneurial activities will find the cases both interesting and useful. The case of PSA Peugeot Citroën's electric passenger car is an example of an innovation perceived as a failure because of its disappointing sales volume. Yet, by limiting our assessment of the electric passenger car to a short-term perspective, we may miss out on an essential part of its value. As part of a wider innovation process, the electric passenger car project is a significant step for PSA in its expertise regarding electric vehicles. Key learning outcomes: (a) to understand that innovation is a complex process with fuzzy frontiers, both in time and space; (b) to understand that innovation is a long-term investment with spillovers into other projects; (c) to be aware of the multiple perspectives that may be adopted when examining innovation; and (d) to be aware of the impact of labelling a project a failure.

The Impact

All over the world at present, injuries and fatalities from road accidents are a significant problem, especially occurred to pedestrians from passenger cars. Most of the fatal accidents between car and pedestrians prove deadly because of the head to hood impact. This paper aims to develop a bumper to avoid from passenger car’s fatal head impact for pedestrian protection, and most importantly, the impact of different objects with passenger car bumper needs to be recognized. Firstly, a pendulum system is constructed to perform the fundamental research which is concentrated on the response pattern of impact-object simulation tests, and we confirmed the application possibility for the method of discriminable pattern recognition whether impact-object is human-like or not by means of neural networks using smart PZT materials. Finally, the impact characteristics analyses can provide enough pattern recognition indices which can be developed and then used to recognize the impact information by two different neural networks.

Introduction: The market of cars is an important indicator of the socio-economic well-being of the population, since the purchase of a car, as a rule, marks the achievement by individuals of full satisfaction of primary needs and stability in cash receipts. At the same time, conditions for the functioning of the passenger car market differ considerably in the regions, which complicates the effective management of the development of the passenger car market at the national level.Hypothesis of scientific research. It is assumed that the functioning of regional markets for passenger cars is largely determined by the influence of certain indicators of socio-economic development of the regions. Identification of the availability, nature and strength of the impact of indicators of socio-economic development of regions on the functioning of regional markets of passenger cars will improve the efficiency of management of the development of the national market of passenger cars.The purpose of the article is to develop the methodological principles of management of the national market of passenger cars through the development of methodical tools for the typology of regional markets of passenger cars.Methods of research: method of expert poll – to determine the list of indicators of socio-economic development of regions that influence the functioning of regional markets of passenger cars; the method of theoretical generalization – for the formation of the methodology of typology of regional markets of passenger cars on the most significant indicators of socio-economic development of regions.Results: the methodology of typology of regional markets of passenger cars was developed, which provides clusterization of passenger car markets at the regional level by types: "production oriented market", "socially oriented market", "trade-oriented market", "financially investment-oriented market", "innovative oriented market"," mixed market".Conclusions: the development of methodological tools for the typology of regional markets of passenger cars contributes to the further development of methodical principles of management of the national market of passenger cars in the direction of strengthening the target direction and, thus, increasing the effectiveness of managerial influence on the processes taking place in the market of passenger cars on the meso-, and at macro levels.

The Impact

In the 2016 Highway Capacity Manual (HCM-6), the impact of trucks on freeway operations is measured by passenger car equivalents (PCEs). PCEs are estimated by the equal capacity methodology. The HCM-6 PCE values are based on the assumptions that passenger cars and trucks travel at the same free-flow speed, that they travel on freeways with three lanes per direction, and that they travel in traffic with no more than 25% trucks. On Interstate 80 in western Nebraska, it is observed that the interaction of high truck percentages and large speed differences between passenger cars and trucks may result in moving bottlenecks. It was hypothesized that the current HCM-6 PCEs may be not appropriate for these conditions. A companion paper showed this was true and that the major cause was speed differentials between trucks and passenger cars. In essence, when slow-moving trucks pass each other they create moving bottlenecks, which results in increased PCE values. This paper is an extension to a companion paper and examines a number of issues related to estimation of PCEs. The paper examines the effect of speed limit, truck passing restrictions, and data aggregation interval on PCEs. The results show that: (i) if a higher speed limit is implemented, trucks will affect the passenger cars more severely; (ii) if truck passing is restricted by lane restrictions, the negative impacts of trucks on passenger car operation may be mitigated; and (iii) using a longer data aggregation interval results in lower PCE values, all else being equal.

The Impact

The purpose of the work is to increase comfort and safety of railway passenger transportation, at the expense of passenger car body vibration load decrease. The analysis of the investigations carried out and dedicated to the definition of rigidity property impact upon the level of passenger comfort and traffic safety has shown that the first mode of vertical bending impacts considerably upon car body dynamic behavior. The analysis of vibration load impact upon passenger car body was carried out in accordance with Dumitriu’s technique. As apposed to the investigations carried out earlier in the paper the data on car metal structure acceleration are obtained through the methods of mathematical modeling based on solid and finite element models. On the basis of the data obtained and natural running tests there was created and verified a particularized lamellar finite-element model of a car body with the aid of which there were obtained values of vertical and horizontal accelerations of a car body metal structure. The analysis of the results obtained has shown that within the frequency range of 8.9. – 20 Hz there are observed acceleration surges which are among the most sensitive ones in terms of the impact upon man and transport comfort support. At the frequencies obtained there was carried out a passenger comfort investigation with the aid of which it was defined that at the frequency of car body own bending oscillations of 8.9 Hz – a comfort index is above 4 units that shows a low comfort level. A frequency of 8.9 Hz corresponds to a vertical bending mode which is the most significant mode of car body deformation in terms of passenger comfort support. With regard to this in the works there was offered a number of efficient measures for strengthening car body structure bearing capacity with the goal of its bending rigidity increase which provides an installation of a supplementary bearing partition in the mid-section of a car body, and also the introduction of auxiliary longitudinal elements in a frame supporting design. For the effectiveness assessment of measures offered there was carried out re-investigation according to the technique described. As a result of the computation it was defined that the design measures offered allowed increasing a frequency value of own bending vibration of car body metal structure up to 11.7 Hz. The analysis of the results obtained allowed drawing a conclusion of the effectiveness of design solutions offered on car body vibration load decrease.

The Relationship

This paper aimed to research the relationship between the wrap around distance (WAD) to head contact and vehicle impact speed based on real pedestrian traffic accidents with video. A team was established to collect passenger car-pedestrian accident cases occurring between July 2011 and July 2015 in Chongqing, China. A total of 15 pedestrian crashes were selected into the sample. Impact speeds were calculated by a video analysis technology, and the WAD was revised according to the average height of pedestrians involved in the sample. The relationship between the WAD and impact speed was analyzed using linear regression analysis. We propose a method to evaluate the impact speed in passenger car-pedestrian. These results will contribute to the development of judicial identification and research of pedestrian injury.
