A | 8月26日消息，据报道，近日，内蒙古呼和浩特一处道路正在开展施工作业，现场设置的有围挡与交通锥对道路进行封闭管控。 Colombo, Oct 17 (UNI) Sri Lanka saw its earnings from the tourism trade fall in September for a second consecutive month due to weaker arrivals ahead of a more prospective season which has got underway from the start of October and ends in January.
According to the data available through September, tourism trade has brought in $ 53.6 million in foreign exchange, bringing the cumulative nine-month earnings to $ 946.4 million, the Daily Mirror reported on Monday.
The September earnings were lower than both July and August when the figures for those two months were $ 85.1 million and $ 67.9 million respectively.
In the same month a year earlier, the trade had earnings of $ 35.3 million from 13, 547 visitors when the country was under lockdowns, the newspaper said.
In this September, 29,802 tourists travelled to Sri Lanka which was below 37, 760 arrivals in August and 47,293 arrivals in July.
Sri Lanka’s monthly arrivals exceeded 100,000 through March as the country got off to a fine start to tourism with high hopes of the foreign exchange it could generate in 2022, after two years of near decimation of the industry due to the pandemic, the report said.
In the nine months, Sri Lanka has welcomed 526,232 visitors as tourists.
With the start of the winter season in Europe, Sri Lanka is looking at a possible increase in bookings, specially from countries such as Germany and Switzerland.

B | 一辆无人快递车没有识别到这些设施径直驶向了施工围挡区域，现场工作人员多次示意车辆停下均没有效果，随后，工作人员情绪激动拿起反光锥砸向了车辆。 对此，无人快递车的工作人员回应称，该无人车依靠摄像头与激光雷达感知周边环境，由车载系统做出行驶决策。
C | 如果激光雷达、视觉传感器表面沾染雨水、污物，就有可能出现识别失效，无法识别交通锥这类道路隔离设施。
不止这一例，另一起相似事故，也暴露出了无人配送车在算法逻辑上的不足。
一台无人快递车在路上行驶时与货车相遇，因为道路比较窄两车无法通过，且货车体型较大倒车也不好倒。面对这种情况，无人车既不绕行也不后退，愣是在原地跟货车僵持了近20分钟。 后来没办法，现场有人调来了一辆叉车，直接将无人车叉起搬离了车道。对于此事不少网友表示，无人配送设备在简单场景下能够正常完成配送任务，但在会车占道这类复杂真实路况中，算法仍有待优化，不能只会机械原地等待。
