Dynamic Traffic Monitoring

Chapter -1: General Introduction

• Traffic monitoring is a process of reviewing, analyzing and managing traffic for any abnormality or process that can affect network performance or security.
• It is a process that uses various tools and techniques to study computer based traffic. Traffic monitoring generally requires reviewing each incoming and outgoing packet.
Traffic phenomena are complex and nonlinear, depending on the interactions of a large number of vehicles. Due to the individual reactions of human drivers, vehicles do not interact simply following the laws of mechanics, but rather show phenomena of cluster formation and shock wave propagation both forward and backward, depending on vehicle density in a given area. Some mathematical

This PCU factor is the ratio of the projected rectangular area of the vehicle type, as a proportion of that of a car, to the velocity of the vehicle type, as a proportion of car velocity. The velocities for different vehicle types are found by solving a set of linear simultaneous equations, whose coefficients depend on: (1) traffic stream composition; (2) the road's total mixed traffic flow per unit time; (3) total carriageway width; and (4) parameters to be estimated by linear regression analysis. Variations of dynamic PCUs are plotted, in relation to traffic composition, for a section of the Delhi Ring Road, for the following vehicle classes: (1) car/jeep/taxi; (2) bus/minibus/truck; (3) motorized three-wheeler; (4) motorized two-wheeler; and (5) bicycle. Speed-flow relationships and road capacity estimates are also

PROPERTIES OF GOOD TRAFFIC MONITORING SYSTEM:
• Adaptive to changes in the real world environments
• Easy to set up.
• Capable of operating independently of human operators.
• Capable of intelligent decisions.
• Capable of monitoring multiple cameras and continuous operation.

PLAN OF THE WORK (METHODOLOGY):

• PROBLEM IDENTIFICATION.
1. Road characteristics
2. Vehicular characteristics
3. Traffic flow

• SITE SDAELECTION
1. The intersection having congestion in flow.
2. The intersection which allows regular flow of traffic.

• DATA COLLECTION
1. Video graphic survey on both sites.
2. Vehicle count study in particular time.
3. Necessary details of the selected site.

• DATA EXTRACTION

1. By reducing the capacity up to 10-20%, we compare the base value with the saturated value.
2. In saturated conditions the design due to other movements at intersections by our study we can modify the design and develop better conditions.
