Case Study:

Tren Urbano

Conclusions

Strengths

This case study illustrates how accessibility measures, derived from travel demand model output, can be used to measure the distribution of benefits of alternative transportation projects. Some of the advantages of the approach taken here include:

• By working with data in a GIS environment, the spatial distribution of current accessibility levels as well as future changes in accessibility can be displayed.
• Accessibility levels and changes can be associated with socioeconomic data available at the TAZ level (in this case, median income) to estimate how current accessibility and benefits may vary by socioeconomic group.
• The use of a multimodal travel model means that accessibility can be compared between automobile and transit modes. This can provide further insight into the equity of alternative transportation investments.
