Existing Capacity

4. YEAR 2020
 Almost 250,000 jobs will be added (16%)
 The population will grow by nearly 400,000 people (13%)
 Nearly 87,000 new homes will be built (9%)
 Vehicle miles traveled will increase by 10% on freeways
 Peak travel speeds will reduce 10%
 Average commute time will increase almost 20%

5. Operational Objectives
 Improve safety and mobility
 Reduce congestion and manage demand
 Provide information to motorists
 Share information with stakeholders

6. Challenges of Meeting Objectives
- Congestion
- Growth in demand
- Daily delay
- Limited funding

Approach to
Managing
Transportation
 Predict future (long
range) traffic volumes
 Fund major capital
projects to provide
additional capacity
 Addresses 45% of the
congestion problem
 Difficult to provide new
capacity
