Transportation information collection and communication plays a key role in intelligent transportation system (ITS). Unfortunately, most conventional ITSs can only detect the vehicle in a fixed position, and their communication cables and power cables elevate the cost of construction and maintenance. Because of the advantages of the wireless sensor network (WSN) such as low power consumption, wireless distribution, and flexibility without cable restrictions., the usage of WSN in ITSs is expected to be able to overcome the above difficulties. This paper proposes a WSN-based transportation information collection and communication system. Hardware and software WSN modules are designed and prototyped
