So what have we done about it?
Let’s look at…
• Freeway Traffic Management
• Arterial Traffic Management
• Traveler Information

Recent Freeway-Mgmt. Innovations
1. Freeway-to-Freeway metering (I-105)
2. System-Wide Adaptive Ramp Metering (I-210)
3. HOT lane (SR-91); Managed Lane (I-15)
4. Private Toll Road (SR-125 in San Diego)
5. Integrated Incident-Response System (L.A.)
6. More…

Recent Arterial Innovations
1. IEN – L.A. County (more in next pres.)
2. IMTMS – San Diego (more in next pres.)
3. Adaptive Signal Control – LADOT
4. Rapid Bus (29 corridors) – MTA & LADOT
5. and certainly more…
.
33
Future View: Arterial Management Directions
1. More adaptive signal control
2. Multi-city signal coordination
3. Multi-modal coordination & signal priority
4. Integrated corridor management
5. Extensive data sharing; some shared control
6. Vehicle Infrastructure Integration (VII)
7. Intersection collision avoidance - CICAS
8. More….

Historical View:
Traveler Information Innovations
TravInfo:• San Francisco Bay area • Began 1994 (Internet), 1996 (phone)• Initial Info: Transit; fwy incidents, congestion• Early call volumes: ~50K per month
1-800-COMMUTE:• Southern Calif. except San Diego• Began 1994 (phone) as a “Gateway”• Initial Info: (static) Bus, roads, rideshare, …
36
Current View: Traveler Information Innovations
MTA “RIITS” (L.A. County)• Web maps: freeway & arterial congestion;
incidents, CCTV, DMS, bus & rail tracking. • Event data base for local agencies
SANDAG 511 (San Diego County)• Phone (IVR) • Internet (freeway speeds, incidents, …)
Private ISP’s (SoCal, SF Bay Area)• Internet, Phone; Cable TV, PDAs, more…
