How infrastructure paves the way in India:
In the U.S. Midwest, there are said to be two seasons: winter and road construction. But in India, the rapid growth of car ownership is not as well supported by the infrastructure.
3,625 miles of national highways connect 19 of the largest Indian cities, encircling the country. And progress is slower than planned. For example, from April to June 2006, only 986 kilometers (about 612 miles) of the nation's highways were upgraded, missing the target by nearly 14 percent.
Existing roads in India's large cities continue to be plagued by overcrowding, with large delivery trucks, three-wheelers, two-wheelers, pedestrians and the occasional ox-drawn cart jostling for space. So, even though some people can afford larger cars, smaller cars are the face of India's automotive future.
The people's car hits the road
In a market dominated by two-wheelers, owning a four-wheeler is an upgrade in status and space. But not too much space. The Tata Group's "1-lakh car" will sell for $2500 and offer enough trunk space for a small duffel bag. But when families of four are a common sight on scooters, even that is a luxury.
How infrastructure paves the way in China:
China is in the midst of building a massive concrete and asphalt circulatory system. With a total highway length of more than 1.8 million kilometers (over a million miles) in 2003, China now has the second longest highway system in the world. In 2005, China's State Council announced its long-term National Expressway Network Plan to increase the expressways by a factor of four through 2035, in order to connect all cities with populations larger than 200,000. This will better link rural China with its urban centers.

However, compared to efforts to build more vehicles and roads, the government has paid less attention to traffic management. Traffic management is an integrated activity involving traffic planning, traffic-flow control and congestion management for the safe and efficient movement of people and goods. So the biggest challenge for the government is simultaneously managing road construction, traffic congestion and driver behavior patterns.
