PROBLEM AREA :

Average Daily Traffic in this area has been constant throughout the years (since about 2000 it has averaged 50-55,000 vehicles per day). In the future, the traffic is anticipated to experience some growth, about 5% between 2020 and 2045, due to planned development in the study area. 
​
Northwest Highway has multiple intersection issues from Inwood Road to Hillcrest Road. Some of the major traffic issues are listed below :

1. The intersection of Inwood Road and Northwest Highway: Northbound and Southbound left-turns experience high delays during the AM peak hour period, whereas Eastbound and Westbound left-turns also experience high delays during the PM peak hours.
2. The intersection of the Dallas North Tollway and Northwest Highway: The Northbound approach experiences high delays during peak periods. Westbound left-turn queues block a lane of traffic during the PM peak hour period. The Southbound approach also experiences high delays during peak periods. Eastbound left-turn queues block a lane of traffic during the PM peak period.
3. The intersection of Douglas Avenue and Northwest Highway: Southbound through movements experience high delays during peak periods. Northbound right-turns experience high delays during the PM peak period. The Fire Station signal causes confusion and frustration when out of sync with the signal timing.
4. The intersection of Preston Road and Northwest Highway: The Left-turns movement experience high delays during the PM peak period. Long Westbound queues occur during the AM peak periods and long Eastbound queues occur during the PM peak period.
5. The intersection of Pickwick Lane and Northwest Highway: Southbound left-turns experience high delays during peak periods.
6. The intersection of Thackery and Northwest Highway: Northbound and Southbound left-turn and through movements experience high delays during peak periods.
7. The intersection of Hillcrest Avenue and Northwest Highway: The Northbound approach experiences high delays during peak periods. The Southbound left-turn experiences high delays during peak periods.
