Traffic Management System - Civil Project

Transportation Engineering

Intelligent Traffic
Management

Design a traffic system that dynamically changes signal timings based on vehicle density. Master Sensor Integration, Webster's Formula, and Phase Sequencing.

SIGNAL LAB

PHASE 1 (N-S) STOP

Traffic Density (N-S): HIGH

Traffic Density (E-W): LOW

DESIGN PROCESS

Key steps for signal timing and junction design.

ITS

Traffic Survey

Conduct detailed volume counts (PCU/hr) for all intersecting arms during peak flow hours.

Cycle Design

Determine Optimum Cycle Time (C0) using Webster's formula and calculate Green Time for each phase.

Controller Setup

Install Controller Unit (Microcontroller/PLC). Connect signal outputs and vehicle sensors (loops/IR) for real-time data.

Density Logic

Program the controller to extend green time for phases with high sensor activity (Intelligent Traffic System).

Signal Timing Calculation

// Optimum Cycle Time (Webster's Formula - Simplified) // Inputs L = 10; // Total Lost Time (sec) per cycle Y = 0.5; // Sum of Critical Flow Ratios (y1 + y2) I = 4; // Inter-green time // Webster's Optimal Cycle Time (C0) // C0 = (1.5 * L + 5) / (1 - Y) C0 = (1.5 * 10 + 5) / (1 - 0.5); C0 = 20 / 0.5 = 40 seconds; // Effective Green Time (G_eff) G_eff = C0 - L; // 40 - 10 = 30 seconds // Allocated Green Time (Gi) // Gi = (y_i / Y) * G_eff; // Example: G(NS) = (0.3 / 0.5) * 30 = 18 seconds // Example: G(EW) = (0.2 / 0.5) * 30 = 12 seconds
