Identification of critical traffic conditions based on analysis of traffic variables in a route allows the planners to react timely under such conditions. In this paper, a Decision Support System (DSS) is proposed to determine traffic condition in a route based on the data traffic variables received online in a route such as speed and flow. A knowledge based system is established, which consists of a series of rules (If-Then) to identify the critical traffic conditions when the traffic variables in a route decrease or increase as compared with the previous means, significantly. Statistical control charts are used to identify significant deviations of traffic variables from their means, which are usually caused by events such as accidents. The data for traffic variables, namely flow and speed in 60 hours was collected from one of the main highways of Tehran (Iran’s Capital) in peak hours (17 and 18). 35 observations were used to design control limits for two traffic variables, namely flow and speed and the remaining 25 observations were used to monitor traffic conditions in the future (execution of phase 2 of statistical control charts). The results of traffic monitoring in the intended route indicate that the decision support system has a good performance to identify critical traffic conditions.

This paper presents an empirical investigation to study the relationship between emotional intelligence and job performance in railroad industry. The study uses two questionnaires, one for measuring emotional intelligence adopted from Salovey and Mayer (1989) [Salovey, P., & Mayer, J. D. (1989). Emotional intelligence. Imagination, Cognition and Personality, 9(3), 185-211.] and the other one for measuring job performance. The study selects 300 full time employees who work for railroad industry in city of Tehran, Iran, distributes two questionnaires among the employees and managed to collect all filled ones. Using Spearman correlation, the study has determined a positive and meaningful relationship between emotional intelligence and job performance (r = 0.796, Sig. = 0.000). In addition, there were positive and meaningful relationships between four components of emotional intelligence, namely consciousness (r = 0.642, Sig. = 0.000), self-regulation (r = 0.41, Sig. = 0.000), self-awareness ( r = 0.552, Sig. = 0.000) and social skills (r = 0.524, Sig. = 0.000).

One of the primary economic issues is associated with optimum resource allocation in profitable investments with reasonable risk. For this purpose, performance measurement’s criteria are needed some of which emphasize cash flow variables and some others focus on information content of accounting profit. On this basis, this study examines the relationship between earnings before tax and interest and operational cash flows with stockholders’ return in Tehran Stock Exchange (TSE). In this regard, information asymmetry was also examined. To test hypotheses, multivariable regression and combined data method were used. The results showed that based on the information of 102 companies in stock market from 2004 to 2009, there was a positive and significant correlation between earnings before interest and tax and stock return in the companies. While, operational cash flow has no significant impact on stock return. Increasing information asymmetry, earnings before interest and tax has a positive and significant correlation with stockholders ’return; but operational cash flow has no significant effect on stockholders’ return. In other words, earnings before interest and tax have higher information content than operational cash flow.
