A pair of new mobile apps hopes to help Palestinians navigate their way around snarled traffic at Israeli checkpoints in the West Bank, offering a high-tech response to an intractable problem: constant, burdensome and often seemingly random restrictions on movement. "Azmeh," which means traffic jam in Arabic, and "Qalandiya," the name of a major Israeli checkpoint on the outskirts of Jerusalem, join a slew of other global traffic apps, including the Israeli-developed Waze. What sets the two Palestinian apps apart is how they go beyond daily rush hour traffic and touch at the heart of a central Palestinian criticism of Israeli occupation.
