A Videogrammetric Analysis of On Peak/Off Peak Traffic Density: A Case of Board Bazaar Peshawar

The increasing population is a growing issue in densely populated cities, which leads to an increase in transportation services. In this paper travel time delay due to stationary bottleneck was observed throughout the week in one of the densely populated cities of Pakistan i.e. Peshawar. Videogrammetry was implemented to obtain the recorded frames through the various days of the week. The recorded frames were then statistically analyzed to identify the travel delays in Board Bazaar Peshawar at a stationary bottleneck using SPSS and Statgraphics Software. The statistical analysis revealed a direct proportionality between traffic density and travel time, whereas an inverse proportionality was identified between traffic speed and traffic density. A high traffic density was observed on working days, whereas on the non-working days a reduced traffic density was observed. This study recommends a predictive target lane vehicular guidance system for a smooth traffic flow.

On Eccentric and Polynomial Based Descriptors of Graphical Structures

In chemical graph theory, numerical parameters which characterizes the molecular topology and structure of a graph are de ned as topological indices. In QSAR/QSPR di erent theoretical properties of chemical compounds as well as molecular topological in- dices such as eccentric connectivity index (ECI ), modi ed eccentric connectivity (MECI), total eccentricity (TE), connective eccentricity index (CEI ), Zagreb indices, counting polynomials and many more are used to predict the bioactivity of chemical compounds. The purpose of this thesis is to compute the characteristics of distance based topological indices in certain graphs which also covers computation of distance based topological in- dices for some type of nanostructure such as dendrimers, nanocones, few networks and counting polynomials of Benzene structure which is embedded in periodic type surface.
