The Subject: Maximizing Urban Access 650 BC TO 2000 • Urban access can be measured from the urban area level to between small zones within the urban area. Urban access may be defined as follows: • Urban access is the percentage of metropolitan area employment that can be reached (door-to- door) by the urban transport system in a specified period of time (such as 30 minutes).

Why Cities Grow (Their Purpose) ALAIN BERTUAD, FORMER WORLD BANK PLANNER – The raison d’être of large cities is the increasing return to scale inherent to large labor markets. The cities’ economic efficiency requires, therefore, avoiding any spatial fragmentation of labor markets.

Coming to Terms with Global Urban Expansion
African Cities are Too Large for Walking ALREADY TOO SPATIALLY LARGE • . The cities of developing Africa may have long since become too spatially large for walking to suffice as a principal mode of access without hobbling economic growth and ingraining high levels of poverty.
Autos in All Western Europe & North America MAJORITY OF MOTORIZED TRAVEL IS AUTO IN ALL CITIES Example PORTLAND Transit +Cycle+Walk Market Share Down 9% 1980-2011
CAR & 2-WHEELER Provides access to within walking distance of all points in the urban area
STRENGTHS AND WEAKNESSES OF MASS TRANSIT For most trips mass transit is not available or feasible
YOU CANNOT EXPECT PEOPLE TO MAKE IRRATIONAL CHOICES

2-Wheelers & Personal Mobility HO CHI MINH CITY
Dapice, Gomez-Ibanez, & Thanh ON HO CHI MINH CITY & MOTORCYCLES • ...the motorcycle offers many of the conveniences of a private automobile, such as on-demand, door-to-door service, and the ability to make intermediate stops and carry packages and extra passengers. Many Vietnamese have more than one job and children to drop off and pick up at school, and thus value the flexibility of a motorcycle.

Policies for Urban Access BASED UPON PRUD’HOMME/LEE & OTHERS • Employment (Enterprise) access: The employee access indicator would estimate the number of jobs in an urban area that can be reached by workers from specific zones and overall within a fixed period (such as 30 minutes). • Employee (Worker) access: The work force access indicator would estimate the number of potential employees in an urban area that could reach employment locations in specific zones and overall within a fixed period (such as 30 minutes). • Cost per reduced delay hour (Texas Governor’s Business Council)
