A Weighted Methodology for Access Density Analysis

Abstract:

OUTLINE

  • INTRODUCTION

  • APPLICATIONS

  • OBJECTIVES

  • METHODOLOGY

  • DATA COLLECTION

  • DATA ANALYSIS

  • STATISTICAL TESTS

  • RECOMMENDATIONS AND CONCLUSIONS

 

OBJECTIVES

1. To conduct a thorough literature review to study the existing methods of computing access density

2. To apply different computational methods of access density and studying their differences

3. To develop a weighted methodology and studying its performance

4. To make recommendations regarding the most suited methodology

 

CONCLUSIONS AND RECOMMENDATIONS

  • There are various methods of computing access density in previous studies and a standard methodology could be defined.

  • All 3 components should be considered

1. Both direction driveways

2. Type of intersection’s (signalized + un-signalized)

3. Type of median opening’s

  • Weighted methodology should be preferred to obtain access density which shows improved correlation to crash rate

  • Weighted methodology 2 is recommended as it eliminates the drawbacks of weighted methodology 1 and adds flexibility in application to all possible access types.
