So what have we done about it?

Let’s look at…

• Freeway Traffic Management

• Arterial Traffic Management

• Traveler Information

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….

4. Traveler Information in California

35

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…
