4
Objectives

• Upgrade the location of signs
• Find alternative driving directions

5
Problem Recognition

• System Environment
• Industrial District
• Street Quality
• Slopes and elevations
• Rails
• Controlled System
• Only one inlet
• Streets leading to the inlet

6
System Environment

• Industrial District

- OMSI is located in an industrial district that
is surrounded by lot of warehouses.
N
OMSI
7

• System Environment

• Street Quality

- Most streets are in bad condition
8

• System Environment

• Slopes and elevation

- OMSI happens to be located at a low elevation
(34 ft) compared to its surroundings (55 ft).

• System Environments

• Rails

• - Trains delay traffic at certain times
• Old rails make the streets undesirable to
  motorists

• Controlled System

• Only one inlet

- This adds another type of difficulty

Problem Definition

• The problem can be stated as
• Getting people to OMSI with a clear directions
  and enough signs

15
Methodology

• Measure of Performance
• Generation of Alternatives

16
Measure of Performance

• Constraints Quality, speed, Volume
• Objectives Delay, signs.

17

• Measure of Performance

• Constraints Quality
• Pavement (cracking)
• Marking
• Geometric characters (width, bike lane, median)

Scale 4 (Excellent) to 1 (Poor)
18

• Measure of Performance

• Constraints Speed, Volume

19

• Measure of Performance

• Objectives Delay

• Most streets carry big trucks.
• Train passes frequently many times a day.

20

• Measure of Performance

• Objectives Signs

• Signs should be consistent

21

• Generation of Alternatives

N

• Current routes and signs

22

• Generation of Alternatives

N

• Current routes and signs

23

• Outcomes

N

• 5 signs removed
• 2 signs added
• 2 new routes
