• 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.
